How do I get the current file's directory path?
I tried:
>>> os.path.abspath(__file__)
'C:\\python27\\test.py'
But I want:
'C:\\python27\\'
The special variable __file__ contains the path to the current file. From that we can get the directory using either pathlib or the os.path module.
Python 3
For the directory of the script being run:
import pathlib
pathlib.Path(__file__).parent.resolve()
For the current working directory:
import pathlib
pathlib.Path().resolve()
Python 2 and 3
For the directory of the script being run:
import os
os.path.dirname(os.path.abspath(__file__))
If you mean the current working directory:
import os
os.path.abspath(os.getcwd())
Note that before and after file is two underscores, not just one.
Also note that if you are running interactively or have loaded code from something other than a file (eg: a database or online resource), __file__ may not be set since there is no notion of "current file". The above answer assumes the most common scenario of running a python script that is in a file.
References
pathlib in the python documentation.
os.path - Python 2.7, os.path - Python 3
os.getcwd - Python 2.7, os.getcwd - Python 3
what does the __file__ variable mean/do?
Using Path from pathlib is the recommended way since Python 3:
from pathlib import Path
print("File Path:", Path(__file__).absolute())
print("Directory Path:", Path().absolute()) # Directory of current working directory, not __file__
Note: If using Jupyter Notebook, __file__ doesn't return expected value, so Path().absolute() has to be used.
In Python 3.x I do:
from pathlib import Path
path = Path(__file__).parent.absolute()
Explanation:
Path(__file__) is the path to the current file.
.parent gives you the directory the file is in.
.absolute() gives you the full absolute path to it.
Using pathlib is the modern way to work with paths. If you need it as a string later for some reason, just do str(path).
Try this:
import os
dir_path = os.path.dirname(os.path.realpath(__file__))
import os
print(os.path.dirname(__file__))
I found the following commands return the full path of the parent directory of a Python 3 script.
Python 3 Script:
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
from pathlib import Path
#Get the absolute path of a Python3.6 and above script.
dir1 = Path().resolve() #Make the path absolute, resolving any symlinks.
dir2 = Path().absolute() #See #RonKalian answer
dir3 = Path(__file__).parent.absolute() #See #Arminius answer
dir4 = Path(__file__).parent
print(f'dir1={dir1}\ndir2={dir2}\ndir3={dir3}\ndir4={dir4}')
REMARKS !!!!
dir1 and dir2 works only when running a script located in the current working directory, but will break in any other case.
Given that Path(__file__).is_absolute() is True, the use of the .absolute() method in dir3 appears redundant.
The shortest command that works is dir4.
Explanation links: .resolve(), .absolute(), Path(file).parent().absolute()
USEFUL PATH PROPERTIES IN PYTHON:
from pathlib import Path
#Returns the path of the current directory
mypath = Path().absolute()
print('Absolute path : {}'.format(mypath))
#if you want to go to any other file inside the subdirectories of the directory path got from above method
filePath = mypath/'data'/'fuel_econ.csv'
print('File path : {}'.format(filePath))
#To check if file present in that directory or Not
isfileExist = filePath.exists()
print('isfileExist : {}'.format(isfileExist))
#To check if the path is a directory or a File
isadirectory = filePath.is_dir()
print('isadirectory : {}'.format(isadirectory))
#To get the extension of the file
fileExtension = mypath/'data'/'fuel_econ.csv'
print('File extension : {}'.format(filePath.suffix))
OUTPUT:
ABSOLUTE PATH IS THE PATH WHERE YOUR PYTHON FILE IS PLACED
Absolute path : D:\Study\Machine Learning\Jupitor Notebook\JupytorNotebookTest2\Udacity_Scripts\Matplotlib and seaborn Part2
File path : D:\Study\Machine Learning\Jupitor Notebook\JupytorNotebookTest2\Udacity_Scripts\Matplotlib and seaborn Part2\data\fuel_econ.csv
isfileExist : True
isadirectory : False
File extension : .csv
works also if __file__ is not available (jupyter notebooks)
import sys
from pathlib import Path
path_file = Path(sys.path[0])
print(path_file)
Also uses pathlib, which is the object oriented way of handling paths in python 3.
IPython has a magic command %pwd to get the present working directory. It can be used in following way:
from IPython.terminal.embed import InteractiveShellEmbed
ip_shell = InteractiveShellEmbed()
present_working_directory = ip_shell.magic("%pwd")
On IPython Jupyter Notebook %pwd can be used directly as following:
present_working_directory = %pwd
I have made a function to use when running python under IIS in CGI in order to get the current folder:
import os
def getLocalFolder():
path=str(os.path.dirname(os.path.abspath(__file__))).split(os.sep)
return path[len(path)-1]
Python 2 and 3
You can simply also do:
from os import sep
print(__file__.rsplit(sep, 1)[0] + sep)
Which outputs something like:
C:\my_folder\sub_folder\
This can be done without a module.
def get_path():
return (__file__.replace(f"<your script name>.py", ""))
print(get_path())
How can I delete a file or folder?
os.remove() removes a file.
os.rmdir() removes an empty directory.
shutil.rmtree() deletes a directory and all its contents.
Path objects from the Python 3.4+ pathlib module also expose these instance methods:
pathlib.Path.unlink() removes a file or symbolic link.
pathlib.Path.rmdir() removes an empty directory.
Python syntax to delete a file
import os
os.remove("/tmp/<file_name>.txt")
or
import os
os.unlink("/tmp/<file_name>.txt")
or
pathlib Library for Python version >= 3.4
file_to_rem = pathlib.Path("/tmp/<file_name>.txt")
file_to_rem.unlink()
Path.unlink(missing_ok=False)
Unlink method used to remove the file or the symbolik link.
If missing_ok is false (the default), FileNotFoundError is raised if the path does not exist.
If missing_ok is true, FileNotFoundError exceptions will be ignored (same behavior as the POSIX rm -f command).
Changed in version 3.8: The missing_ok parameter was added.
Best practice
First, check if the file or folder exists and then delete it. You can achieve this in two ways:
os.path.isfile("/path/to/file")
Use exception handling.
EXAMPLE for os.path.isfile
#!/usr/bin/python
import os
myfile = "/tmp/foo.txt"
# If file exists, delete it.
if os.path.isfile(myfile):
os.remove(myfile)
else:
# If it fails, inform the user.
print("Error: %s file not found" % myfile)
Exception Handling
#!/usr/bin/python
import os
# Get input.
myfile = raw_input("Enter file name to delete: ")
# Try to delete the file.
try:
os.remove(myfile)
except OSError as e:
# If it fails, inform the user.
print("Error: %s - %s." % (e.filename, e.strerror))
Respective output
Enter file name to delete : demo.txt
Error: demo.txt - No such file or directory.
Enter file name to delete : rrr.txt
Error: rrr.txt - Operation not permitted.
Enter file name to delete : foo.txt
Python syntax to delete a folder
shutil.rmtree()
Example for shutil.rmtree()
#!/usr/bin/python
import os
import sys
import shutil
# Get directory name
mydir = raw_input("Enter directory name: ")
# Try to remove the tree; if it fails, throw an error using try...except.
try:
shutil.rmtree(mydir)
except OSError as e:
print("Error: %s - %s." % (e.filename, e.strerror))
Use
shutil.rmtree(path[, ignore_errors[, onerror]])
(See complete documentation on shutil) and/or
os.remove
and
os.rmdir
(Complete documentation on os.)
Here is a robust function that uses both os.remove and shutil.rmtree:
def remove(path):
""" param <path> could either be relative or absolute. """
if os.path.isfile(path) or os.path.islink(path):
os.remove(path) # remove the file
elif os.path.isdir(path):
shutil.rmtree(path) # remove dir and all contains
else:
raise ValueError("file {} is not a file or dir.".format(path))
You can use the built-in pathlib module (requires Python 3.4+, but there are backports for older versions on PyPI: pathlib, pathlib2).
To remove a file there is the unlink method:
import pathlib
path = pathlib.Path(name_of_file)
path.unlink()
Or the rmdir method to remove an empty folder:
import pathlib
path = pathlib.Path(name_of_folder)
path.rmdir()
Deleting a file or folder in Python
There are multiple ways to Delete a File in Python but the best ways are the following:
os.remove() removes a file.
os.unlink() removes a file. it is a Unix name of remove() method.
shutil.rmtree() deletes a directory and all its contents.
pathlib.Path.unlink() deletes a single file The pathlib module is available in Python 3.4 and above.
os.remove()
Example 1: Basic Example to Remove a File Using os.remove() Method.
import os
os.remove("test_file.txt")
print("File removed successfully")
Example 2: Checking if File Exists using os.path.isfile and Deleting it With os.remove
import os
#checking if file exist or not
if(os.path.isfile("test.txt")):
#os.remove() function to remove the file
os.remove("test.txt")
#Printing the confirmation message of deletion
print("File Deleted successfully")
else:
print("File does not exist")
#Showing the message instead of throwig an error
Example 3: Python Program to Delete all files with a specific extension
import os
from os import listdir
my_path = 'C:\Python Pool\Test\'
for file_name in listdir(my_path):
if file_name.endswith('.txt'):
os.remove(my_path + file_name)
Example 4: Python Program to Delete All Files Inside a Folder
To delete all files inside a particular directory, you simply have to use the * symbol as the pattern string.
#Importing os and glob modules
import os, glob
#Loop Through the folder projects all files and deleting them one by one
for file in glob.glob("pythonpool/*"):
os.remove(file)
print("Deleted " + str(file))
os.unlink()
os.unlink() is an alias or another name of os.remove() . As in the Unix OS remove is also known as unlink.
Note: All the functionalities and syntax is the same of os.unlink() and os.remove(). Both of them are used to delete the Python file path.
Both are methods in the os module in Python’s standard libraries which performs the deletion function.
shutil.rmtree()
Example 1: Python Program to Delete a File Using shutil.rmtree()
import shutil
import os
# location
location = "E:/Projects/PythonPool/"
# directory
dir = "Test"
# path
path = os.path.join(location, dir)
# removing directory
shutil.rmtree(path)
Example 2: Python Program to Delete a File Using shutil.rmtree()
import shutil
import os
location = "E:/Projects/PythonPool/"
dir = "Test"
path = os.path.join(location, dir)
shutil.rmtree(path)
pathlib.Path.rmdir() to remove Empty Directory
Pathlib module provides different ways to interact with your files. Rmdir is one of the path functions which allows you to delete an empty folder. Firstly, you need to select the Path() for the directory, and then calling rmdir() method will check the folder size. If it’s empty, it’ll delete it.
This is a good way to deleting empty folders without any fear of losing actual data.
from pathlib import Path
q = Path('foldername')
q.rmdir()
How do I delete a file or folder in Python?
For Python 3, to remove the file and directory individually, use the unlink and rmdir Path object methods respectively:
from pathlib import Path
dir_path = Path.home() / 'directory'
file_path = dir_path / 'file'
file_path.unlink() # remove file
dir_path.rmdir() # remove directory
Note that you can also use relative paths with Path objects, and you can check your current working directory with Path.cwd.
For removing individual files and directories in Python 2, see the section so labeled below.
To remove a directory with contents, use shutil.rmtree, and note that this is available in Python 2 and 3:
from shutil import rmtree
rmtree(dir_path)
Demonstration
New in Python 3.4 is the Path object.
Let's use one to create a directory and file to demonstrate usage. Note that we use the / to join the parts of the path, this works around issues between operating systems and issues from using backslashes on Windows (where you'd need to either double up your backslashes like \\ or use raw strings, like r"foo\bar"):
from pathlib import Path
# .home() is new in 3.5, otherwise use os.path.expanduser('~')
directory_path = Path.home() / 'directory'
directory_path.mkdir()
file_path = directory_path / 'file'
file_path.touch()
and now:
>>> file_path.is_file()
True
Now let's delete them. First the file:
>>> file_path.unlink() # remove file
>>> file_path.is_file()
False
>>> file_path.exists()
False
We can use globbing to remove multiple files - first let's create a few files for this:
>>> (directory_path / 'foo.my').touch()
>>> (directory_path / 'bar.my').touch()
Then just iterate over the glob pattern:
>>> for each_file_path in directory_path.glob('*.my'):
... print(f'removing {each_file_path}')
... each_file_path.unlink()
...
removing ~/directory/foo.my
removing ~/directory/bar.my
Now, demonstrating removing the directory:
>>> directory_path.rmdir() # remove directory
>>> directory_path.is_dir()
False
>>> directory_path.exists()
False
What if we want to remove a directory and everything in it?
For this use-case, use shutil.rmtree
Let's recreate our directory and file:
file_path.parent.mkdir()
file_path.touch()
and note that rmdir fails unless it's empty, which is why rmtree is so convenient:
>>> directory_path.rmdir()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "~/anaconda3/lib/python3.6/pathlib.py", line 1270, in rmdir
self._accessor.rmdir(self)
File "~/anaconda3/lib/python3.6/pathlib.py", line 387, in wrapped
return strfunc(str(pathobj), *args)
OSError: [Errno 39] Directory not empty: '/home/username/directory'
Now, import rmtree and pass the directory to the funtion:
from shutil import rmtree
rmtree(directory_path) # remove everything
and we can see the whole thing has been removed:
>>> directory_path.exists()
False
Python 2
If you're on Python 2, there's a backport of the pathlib module called pathlib2, which can be installed with pip:
$ pip install pathlib2
And then you can alias the library to pathlib
import pathlib2 as pathlib
Or just directly import the Path object (as demonstrated here):
from pathlib2 import Path
If that's too much, you can remove files with os.remove or os.unlink
from os import unlink, remove
from os.path import join, expanduser
remove(join(expanduser('~'), 'directory/file'))
or
unlink(join(expanduser('~'), 'directory/file'))
and you can remove directories with os.rmdir:
from os import rmdir
rmdir(join(expanduser('~'), 'directory'))
Note that there is also a os.removedirs - it only removes empty directories recursively, but it may suit your use-case.
This is my function for deleting dirs. The "path" requires the full pathname.
import os
def rm_dir(path):
cwd = os.getcwd()
if not os.path.exists(os.path.join(cwd, path)):
return False
os.chdir(os.path.join(cwd, path))
for file in os.listdir():
print("file = " + file)
os.remove(file)
print(cwd)
os.chdir(cwd)
os.rmdir(os.path.join(cwd, path))
shutil.rmtree is the asynchronous function,
so if you want to check when it complete, you can use while...loop
import os
import shutil
shutil.rmtree(path)
while os.path.exists(path):
pass
print('done')
import os
folder = '/Path/to/yourDir/'
fileList = os.listdir(folder)
for f in fileList:
filePath = folder + '/'+f
if os.path.isfile(filePath):
os.remove(filePath)
elif os.path.isdir(filePath):
newFileList = os.listdir(filePath)
for f1 in newFileList:
insideFilePath = filePath + '/' + f1
if os.path.isfile(insideFilePath):
os.remove(insideFilePath)
For deleting files:
os.unlink(path, *, dir_fd=None)
or
os.remove(path, *, dir_fd=None)
Both functions are semantically same. This functions removes (deletes) the file path. If path is not a file and it is directory, then exception is raised.
For deleting folders:
shutil.rmtree(path, ignore_errors=False, onerror=None)
or
os.rmdir(path, *, dir_fd=None)
In order to remove whole directory trees, shutil.rmtree() can be used. os.rmdir only works when the directory is empty and exists.
For deleting folders recursively towards parent:
os.removedirs(name)
It remove every empty parent directory with self until parent which has some content
ex. os.removedirs('abc/xyz/pqr') will remove the directories by order 'abc/xyz/pqr', 'abc/xyz' and 'abc' if they are empty.
For more info check official doc: os.unlink , os.remove, os.rmdir , shutil.rmtree, os.removedirs
To remove all files in folder
import os
import glob
files = glob.glob(os.path.join('path/to/folder/*'))
files = glob.glob(os.path.join('path/to/folder/*.csv')) // It will give all csv files in folder
for file in files:
os.remove(file)
To remove all folders in a directory
from shutil import rmtree
import os
// os.path.join() # current working directory.
for dirct in os.listdir(os.path.join('path/to/folder')):
rmtree(os.path.join('path/to/folder',dirct))
To avoid the TOCTOU issue highlighted by Éric Araujo's comment, you can catch an exception to call the correct method:
def remove_file_or_dir(path: str) -> None:
""" Remove a file or directory """
try:
shutil.rmtree(path)
except NotADirectoryError:
os.remove(path)
Since shutil.rmtree() will only remove directories and os.remove() or os.unlink() will only remove files.
My personal preference is to work with pathlib objects - it offers a more pythonic and less error-prone way to interact with the filesystem, especially if You develop cross-platform code.
In that case, You might use pathlib3x - it offers a backport of the latest (at the date of writing this answer Python 3.10.a0) Python pathlib for Python 3.6 or newer, and a few additional functions like "copy", "copy2", "copytree", "rmtree" etc ...
It also wraps shutil.rmtree:
$> python -m pip install pathlib3x
$> python
>>> import pathlib3x as pathlib
# delete a directory tree
>>> my_dir_to_delete=pathlib.Path('c:/temp/some_dir')
>>> my_dir_to_delete.rmtree(ignore_errors=True)
# delete a file
>>> my_file_to_delete=pathlib.Path('c:/temp/some_file.txt')
>>> my_file_to_delete.unlink(missing_ok=True)
you can find it on github or PyPi
Disclaimer: I'm the author of the pathlib3x library.
I recommend using subprocess if writing a beautiful and readable code is your cup of tea:
import subprocess
subprocess.Popen("rm -r my_dir", shell=True)
And if you are not a software engineer, then maybe consider using Jupyter; you can simply type bash commands:
!rm -r my_dir
Traditionally, you use shutil:
import shutil
shutil.rmtree(my_dir)
I tried to write a simple program for converting PDF files to JPG. The main idea is a simple .exe file that will find all PDF files in the same directory, and after converting them to JPG put them in the new folder.
And I did it! Using pdf2image, my program doing exactly as I want and as .py and as .exe. But, after running this program on another PC I got an error with popper >following Cmd screenshot
So, I understand, the program tries to find a popper. And sure on another PC program can't find it.
I tried --hidden-import, and --onedir, --onefile e.t.c.
Also saw some similar problem here, as:
PyInstaller and Poppler
Include poppler while generating an application using pyinstaller
But, or I do something wrong, or can't clearly understand how to do solutions in this questions.
What should I do?
#P.S. Maybe, there is a better library or module to create this kind of program?
Whole code:
import os
import pdf2image
from pdf2image import convert_from_path
from inspect import getsourcefile
from pdf2image.exceptions import (
PDFInfoNotInstalledError,
PDFPageCountError,
PDFSyntaxError
)
# Create output direction
# Direction of executable file
script_dir = os.path.abspath(getsourcefile(lambda:0))
# print(script_dir)
output_dir = 'JPG'
# List for files which wasn't converted
error_list = []
# If path don't exist - create
if not os.path.exists(output_dir):
os.makedirs(output_dir)
#print('Path has been created', "\n")
else:
pass
#print('Directory exist', "\n")
# Show all files in directory
file_list = os.listdir()
print(file_list, "List of files")
for file in file_list:
try:
# print(file)
pages = convert_from_path(file, dpi=300, fmt='jpg', output_folder=output_dir, output_file=file)
except Exception as e: print(e)
print("File wasn't converted:", "\n")
if len(error_list) == 0:
print(0, "\n")
else:
for f in error_list:
print(f)
input("Done! Press Enter")
I have the following code:
import datetime as date
import os
import pdfkit
import getpass #Gets me current username
username = getpass.getuser()
path = f"/home/{username}/Data"
relative_path = os.path.relpath(path, os.getcwd())
destination = os.path.join(relative_path, 'data.pdf')
pdfkit.from_url('www.google.com', f'{destination}/data.pdf')
I want the pdf to be saved in windows equivalent of /home/[username]/datafolder. I don't really need to use use linux or mac but for academic reasons i have decided to use the relative path method.
This code makes sense to me but for some reason it is not the directory i want it to be because when i specify the path this way the pdf generator, generates an error.
Error: Unable to write to destination
Exit with code 1, due to unknown error.
I know the error is in the last line of code where i have specified '/relative_path/data.pdf'. Could you please advise how i can resolve this issue?
Update 1:
As suggested by #Matthias I have updated the code but I am still getting the same error
Update 2:
I tried:
from pathlib import Path
destination = Path.home()
try:
os.mkdir(destination\Data)
except OSError as error:
print(error)
But it is still not pointing to the directory Data
Update 3
I know i am getting closer:
import pdfkit
import datetime as date
import calendar
import os.path
import getpass
username = getpass.getuser()
path = f"/home/{username}/Data"
os.makedirs(relative_path, exist_ok=True)
#start = os.getcwd()
relative_path = os.path.relpath(path, os.getcwd())
destination = os.path.join(relative_path, 'data.pdf')
pdfkit.from_url('www.google.com', f'{relative_path}/data.pdf')
At this point the code is executes but the folder Data was not created not am i able to locate data.pdf. I did get sucessful run though:
Loading pages (1/6)
Counting pages (2/6)
Resolving links (4/6)
Loading headers and footers (5/6)
Printing pages (6/6)
Done
Any ideas on how i can get this working correctly? The code does not produce the folder or the file?
Just check by putting
relative_path line before os.makedirs
As below
import pdfkit
import datetime as date
import calendar
import os.path
import getpass
username = getpass.getuser()
#path = os.path.join("home","{username}","Data")
# in case of window you will need to add drive "c:" or "d:" before os.path.sep
path = os.path.join(,"home",username,"Data")
relative_path = os.path.relpath(path, os.getcwd())
os.makedirs(relative_path, exist_ok=True)
#start = os.getcwd()
destination = os.path.join(relative_path, 'data.pdf')
pdfkit.from_url('www.google.com', f'{relative_path}/data.pdf')
Maybe you could change your last line to:
pdfkit.from_url('www.google.com', f'{relative_path}/data.pdf')
in order to get it to save to the home directory.
Perhaps the issue is that the directory doesn't exist. You could use os.makedirs to create the directory, using the exist_ok=True flag in case the directory already exists. Like so:
import datetime as date
import os
import pdfkit
import getpass #Gets me current username
username = getpass.getuser()
path = f"/home/{username}/Data"
os.makedirs(path, exist_ok=True)
pdfkit.from_url('www.google.com', f'{path}/data.pdf')
You can use os.environ. Run this little script on your machine:
import os
for key, value in os.environ.items():
print(key, '-->', value)
and see for yourself what you need exactly. It's portable as well.
Let's say you want to get the path of the user's home directory. You could get it from os.environ['HOME'] and then create the path to the target directory using os.path.join(os.environ['HOME'], 'target_directory_name').
You won't be able to create files in a directory if you don't have the required permissions, though.
User folders in windows are stored in "/Users/{username}/*". I don't know if you are trying to make this compatible for multiple OSs but if you just want to make this run on windows try:
path = f"/Users/{username}/Data"
start = f"/Users/{username}"
Hope it works.:)
Edit:
To get the home directory of a user regardless of OS you could use
from pathlib import Path
home = str(Path.home())
sorry for the late edit.

shutil.rmtree(mydir)
except OSError as e:
print("Error: %s - %s." % (e.filename, e.strerror))
Use
shutil.rmtree(path[, ignore_errors[, onerror]])
(See complete documentation on shutil) and/or
os.remove
and
os.rmdir
(Complete documentation on os.)
Here is a robust function that uses both os.remove and shutil.rmtree:
def remove(path):
""" param <path> could either be relative or absolute. """
if os.path.isfile(path) or os.path.islink(path):
os.remove(path) # remove the file
elif os.path.isdir(path):
shutil.rmtree(path) # remove dir and all contains
else:
raise ValueError("file {} is not a file or dir.".format(path))
You can use the built-in pathlib module (requires Python 3.4+, but there are backports for older versions on PyPI: pathlib, pathlib2).
To remove a file there is the unlink method:
import pathlib
path = pathlib.Path(name_of_file)
path.unlink()
Or the rmdir method to remove an empty folder:
import pathlib
path = pathlib.Path(name_of_folder)
path.rmdir()
Deleting a file or folder in Python
There are multiple ways to Delete a File in Python but the best ways are the following:
os.remove() removes a file.
os.unlink() removes a file. it is a Unix name of remove() method.
shutil.rmtree() deletes a directory and all its contents.
pathlib.Path.unlink() deletes a single file The pathlib module is available in Python 3.4 and above.
os.remove()
Example 1: Basic Example to Remove a File Using os.remove() Method.
import os
os.remove("test_file.txt")
print("File removed successfully")
Example 2: Checking if File Exists using os.path.isfile and Deleting it With os.remove
import os
#checking if file exist or not
if(os.path.isfile("test.txt")):
#os.remove() function to remove the file
os.remove("test.txt")
#Printing the confirmation message of deletion
print("File Deleted successfully")
else:
print("File does not exist")
#Showing the message instead of throwig an error
Example 3: Python Program to Delete all files with a specific extension
import os
from os import listdir
my_path = 'C:\Python Pool\Test\'
for file_name in listdir(my_path):
if file_name.endswith('.txt'):
os.remove(my_path + file_name)
Example 4: Python Program to Delete All Files Inside a Folder
To delete all files inside a particular directory, you simply have to use the * symbol as the pattern string.
#Importing os and glob modules
import os, glob
#Loop Through the folder projects all files and deleting them one by one
for file in glob.glob("pythonpool/*"):
os.remove(file)
print("Deleted " + str(file))
os.unlink()
os.unlink() is an alias or another name of os.remove() . As in the Unix OS remove is also known as unlink.
Note: All the functionalities and syntax is the same of os.unlink() and os.remove(). Both of them are used to delete the Python file path.
Both are methods in the os module in Python’s standard libraries which performs the deletion function.
shutil.rmtree()
Example 1: Python Program to Delete a File Using shutil.rmtree()
import shutil
import os
# location
location = "E:/Projects/PythonPool/"
# directory
dir = "Test"
# path
path = os.path.join(location, dir)
# removing directory
shutil.rmtree(path)
Example 2: Python Program to Delete a File Using shutil.rmtree()
import shutil
import os
location = "E:/Projects/PythonPool/"
dir = "Test"
path = os.path.join(location, dir)
shutil.rmtree(path)
pathlib.Path.rmdir() to remove Empty Directory
Pathlib module provides different ways to interact with your files. Rmdir is one of the path functions which allows you to delete an empty folder. Firstly, you need to select the Path() for the directory, and then calling rmdir() method will check the folder size. If it’s empty, it’ll delete it.
This is a good way to deleting empty folders without any fear of losing actual data.
from pathlib import Path
q = Path('foldername')
q.rmdir()
How do I delete a file or folder in Python?
For Python 3, to remove the file and directory individually, use the unlink and rmdir Path object methods respectively:
from pathlib import Path
dir_path = Path.home() / 'directory'
file_path = dir_path / 'file'
file_path.unlink() # remove file
dir_path.rmdir() # remove directory
Note that you can also use relative paths with Path objects, and you can check your current working directory with Path.cwd.
For removing individual files and directories in Python 2, see the section so labeled below.
To remove a directory with contents, use shutil.rmtree, and note that this is available in Python 2 and 3:
from shutil import rmtree
rmtree(dir_path)
Demonstration
New in Python 3.4 is the Path object.
Let's use one to create a directory and file to demonstrate usage. Note that we use the / to join the parts of the path, this works around issues between operating systems and issues from using backslashes on Windows (where you'd need to either double up your backslashes like \\ or use raw strings, like r"foo\bar"):
from pathlib import Path
# .home() is new in 3.5, otherwise use os.path.expanduser('~')
directory_path = Path.home() / 'directory'
directory_path.mkdir()
file_path = directory_path / 'file'
file_path.touch()
and now:
>>> file_path.is_file()
True
Now let's delete them. First the file:
>>> file_path.unlink() # remove file
>>> file_path.is_file()
False
>>> file_path.exists()
False
We can use globbing to remove multiple files - first let's create a few files for this:
>>> (directory_path / 'foo.my').touch()
>>> (directory_path / 'bar.my').touch()
Then just iterate over the glob pattern:
>>> for each_file_path in directory_path.glob('*.my'):
... print(f'removing {each_file_path}')
... each_file_path.unlink()
...
removing ~/directory/foo.my
removing ~/directory/bar.my
Now, demonstrating removing the directory:
>>> directory_path.rmdir() # remove directory
>>> directory_path.is_dir()
False
>>> directory_path.exists()
False
What if we want to remove a directory and everything in it?
For this use-case, use shutil.rmtree
Let's recreate our directory and file:
file_path.parent.mkdir()
file_path.touch()
and note that rmdir fails unless it's empty, which is why rmtree is so convenient:
>>> directory_path.rmdir()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "~/anaconda3/lib/python3.6/pathlib.py", line 1270, in rmdir
self._accessor.rmdir(self)
File "~/anaconda3/lib/python3.6/pathlib.py", line 387, in wrapped
return strfunc(str(pathobj), *args)
OSError: [Errno 39] Directory not empty: '/home/username/directory'
Now, import rmtree and pass the directory to the funtion:
from shutil import rmtree
rmtree(directory_path) # remove everything
and we can see the whole thing has been removed:
>>> directory_path.exists()
False
Python 2
If you're on Python 2, there's a backport of the pathlib module called pathlib2, which can be installed with pip:
$ pip install pathlib2
And then you can alias the library to pathlib
import pathlib2 as pathlib
Or just directly import the Path object (as demonstrated here):
from pathlib2 import Path
If that's too much, you can remove files with os.remove or os.unlink
from os import unlink, remove
from os.path import join, expanduser
remove(join(expanduser('~'), 'directory/file'))
or
unlink(join(expanduser('~'), 'directory/file'))
and you can remove directories with os.rmdir:
from os import rmdir
rmdir(join(expanduser('~'), 'directory'))
Note that there is also a os.removedirs - it only removes empty directories recursively, but it may suit your use-case.
This is my function for deleting dirs. The "path" requires the full pathname.
import os
def rm_dir(path):
cwd = os.getcwd()
if not os.path.exists(os.path.join(cwd, path)):
return False
os.chdir(os.path.join(cwd, path))
for file in os.listdir():
print("file = " + file)
os.remove(file)
print(cwd)
os.chdir(cwd)
os.rmdir(os.path.join(cwd, path))
shutil.rmtree is the asynchronous function,
so if you want to check when it complete, you can use while...loop
import os
import shutil
shutil.rmtree(path)
while os.path.exists(path):
pass
print('done')
import os
folder = '/Path/to/yourDir/'
fileList = os.listdir(folder)
for f in fileList:
filePath = folder + '/'+f
if os.path.isfile(filePath):
os.remove(filePath)
elif os.path.isdir(filePath):
newFileList = os.listdir(filePath)
for f1 in newFileList:
insideFilePath = filePath + '/' + f1
if os.path.isfile(insideFilePath):
os.remove(insideFilePath)
For deleting files:
os.unlink(path, *, dir_fd=None)
or
os.remove(path, *, dir_fd=None)
Both functions are semantically same. This functions removes (deletes) the file path. If path is not a file and it is directory, then exception is raised.
For deleting folders:
shutil.rmtree(path, ignore_errors=False, onerror=None)
or
os.rmdir(path, *, dir_fd=None)
In order to remove whole directory trees, shutil.rmtree() can be used. os.rmdir only works when the directory is empty and exists.
For deleting folders recursively towards parent:
os.removedirs(name)
It remove every empty parent directory with self until parent which has some content
ex. os.removedirs('abc/xyz/pqr') will remove the directories by order 'abc/xyz/pqr', 'abc/xyz' and 'abc' if they are empty.
For more info check official doc: os.unlink , os.remove, os.rmdir , shutil.rmtree, os.removedirs
To remove all files in folder
import os
import glob
files = glob.glob(os.path.join('path/to/folder/*'))
files = glob.glob(os.path.join('path/to/folder/*.csv')) // It will give all csv files in folder
for file in files:
os.remove(file)
To remove all folders in a directory
from shutil import rmtree
import os
// os.path.join() # current working directory.
for dirct in os.listdir(os.path.join('path/to/folder')):
rmtree(os.path.join('path/to/folder',dirct))
To avoid the TOCTOU issue highlighted by Éric Araujo's comment, you can catch an exception to call the correct method:
def remove_file_or_dir(path: str) -> None:
""" Remove a file or directory """
try:
shutil.rmtree(path)
except NotADirectoryError:
os.remove(path)
Since shutil.rmtree() will only remove directories and os.remove() or os.unlink() will only remove files.
My personal preference is to work with pathlib objects - it offers a more pythonic and less error-prone way to interact with the filesystem, especially if You develop cross-platform code.
In that case, You might use pathlib3x - it offers a backport of the latest (at the date of writing this answer Python 3.10.a0) Python pathlib for Python 3.6 or newer, and a few additional functions like "copy", "copy2", "copytree", "rmtree" etc ...
It also wraps shutil.rmtree:
$> python -m pip install pathlib3x
$> python
>>> import pathlib3x as pathlib
# delete a directory tree
>>> my_dir_to_delete=pathlib.Path('c:/temp/some_dir')
>>> my_dir_to_delete.rmtree(ignore_errors=True)
# delete a file
>>> my_file_to_delete=pathlib.Path('c:/temp/some_file.txt')
>>> my_file_to_delete.unlink(missing_ok=True)
you can find it on github or PyPi
Disclaimer: I'm the author of the pathlib3x library.
I recommend using subprocess if writing a beautiful and readable code is your cup of tea:
import subprocess
subprocess.Popen("rm -r my_dir", shell=True)
And if you are not a software engineer, then maybe consider using Jupyter; you can simply type bash commands:
!rm -r my_dir
Traditionally, you use shutil:
import shutil
shutil.rmtree(my_dir)
