This is what I have:
glob(os.path.join('src','*.c'))
but I want to search the subfolders of src. Something like this would work:
glob(os.path.join('src','*.c'))
glob(os.path.join('src','*','*.c'))
glob(os.path.join('src','*','*','*.c'))
glob(os.path.join('src','*','*','*','*.c'))
But this is obviously limited and clunky.
pathlib.Path.rglob
Use pathlib.Path.rglob from the pathlib module, which was introduced in Python 3.5.
from pathlib import Path
for path in Path('src').rglob('*.c'):
print(path.name)
If you don't want to use pathlib, use can use glob.glob('**/*.c'), but don't forget to pass in the recursive keyword parameter and it will use inordinate amount of time on large directories.
For cases where matching files beginning with a dot (.); like files in the current directory or hidden files on Unix based system, use the os.walk solution below.
os.walk
For older Python versions, use os.walk to recursively walk a directory and fnmatch.filter to match against a simple expression:
import fnmatch
import os
matches = []
for root, dirnames, filenames in os.walk('src'):
for filename in fnmatch.filter(filenames, '*.c'):
matches.append(os.path.join(root, filename))
For python >= 3.5 you can use **, recursive=True :
import glob
for f in glob.glob('/path/**/*.c', recursive=True):
print(f)
If recursive is True (default is False), the pattern ** will match any files and zero
or more directories and subdirectories. If the pattern is followed by
an os.sep, only directories and subdirectories match.
Python 3 Demo
Similar to other solutions, but using fnmatch.fnmatch instead of glob, since os.walk already listed the filenames:
import os, fnmatch
def find_files(directory, pattern):
for root, dirs, files in os.walk(directory):
for basename in files:
if fnmatch.fnmatch(basename, pattern):
filename = os.path.join(root, basename)
yield filename
for filename in find_files('src', '*.c'):
print 'Found C source:', filename
Also, using a generator alows you to process each file as it is found, instead of finding all the files and then processing them.
I've modified the glob module to support ** for recursive globbing, e.g:
>>> import glob2
>>> all_header_files = glob2.glob('src/**/*.c')
https://github.com/miracle2k/python-glob2/
Useful when you want to provide your users with the ability to use the ** syntax, and thus os.walk() alone is not good enough.
Starting with Python 3.4, one can use the glob() method of one of the Path classes in the new pathlib module, which supports ** wildcards. For example:
from pathlib import Path
for file_path in Path('src').glob('**/*.c'):
print(file_path) # do whatever you need with these files
Update:
Starting with Python 3.5, the same syntax is also supported by glob.glob().
import os
import fnmatch
def recursive_glob(treeroot, pattern):
results = []
for base, dirs, files in os.walk(treeroot):
goodfiles = fnmatch.filter(files, pattern)
results.extend(os.path.join(base, f) for f in goodfiles)
return results
fnmatch gives you exactly the same patterns as glob, so this is really an excellent replacement for glob.glob with very close semantics. An iterative version (e.g. a generator), IOW a replacement for glob.iglob, is a trivial adaptation (just yield the intermediate results as you go, instead of extending a single results list to return at the end).
You'll want to use os.walk to collect filenames that match your criteria. For example:
import os
cfiles = []
for root, dirs, files in os.walk('src'):
for file in files:
if file.endswith('.c'):
cfiles.append(os.path.join(root, file))
Here's a solution with nested list comprehensions, os.walk and simple suffix matching instead of glob:
import os
cfiles = [os.path.join(root, filename)
for root, dirnames, filenames in os.walk('src')
for filename in filenames if filename.endswith('.c')]
It can be compressed to a one-liner:
import os;cfiles=[os.path.join(r,f) for r,d,fs in os.walk('src') for f in fs if f.endswith('.c')]
or generalized as a function:
import os
def recursive_glob(rootdir='.', suffix=''):
return [os.path.join(looproot, filename)
for looproot, _, filenames in os.walk(rootdir)
for filename in filenames if filename.endswith(suffix)]
cfiles = recursive_glob('src', '.c')
If you do need full glob style patterns, you can follow Alex's and
Bruno's example and use fnmatch:
import fnmatch
import os
def recursive_glob(rootdir='.', pattern='*'):
return [os.path.join(looproot, filename)
for looproot, _, filenames in os.walk(rootdir)
for filename in filenames
if fnmatch.fnmatch(filename, pattern)]
cfiles = recursive_glob('src', '*.c')
Consider pathlib.rglob().
This is like calling Path.glob() with "**/" added in front of the given relative pattern:
import pathlib
for p in pathlib.Path("src").rglob("*.c"):
print(p)
See also #taleinat's related post here and a similar post elsewhere.
import os, glob
for each in glob.glob('path/**/*.c', recursive=True):
print(f'Name with path: {each} \nName without path: {os.path.basename(each)}')
glob.glob('*.c') :matches all files ending in .c in current directory
glob.glob('*/*.c') :same as 1
glob.glob('**/*.c') :matches all files ending in .c in the immediate subdirectories only, but not in the current directory
glob.glob('*.c',recursive=True) :same as 1
glob.glob('*/*.c',recursive=True) :same as 3
glob.glob('**/*.c',recursive=True) :matches all files ending in .c in the current directory and in all subdirectories
In case this may interest anyone, I've profiled the top three proposed methods.
I have about ~500K files in the globbed folder (in total), and 2K files that match the desired pattern.
here's the (very basic) code
import glob
import json
import fnmatch
import os
from pathlib import Path
from time import time
def find_files_iglob():
return glob.iglob("./data/**/data.json", recursive=True)
def find_files_oswalk():
for root, dirnames, filenames in os.walk('data'):
for filename in fnmatch.filter(filenames, 'data.json'):
yield os.path.join(root, filename)
def find_files_rglob():
return Path('data').rglob('data.json')
t0 = time()
for f in find_files_oswalk(): pass
t1 = time()
for f in find_files_rglob(): pass
t2 = time()
for f in find_files_iglob(): pass
t3 = time()
print(t1-t0, t2-t1, t3-t2)
And the results I got were:
os_walk: ~3.6sec
rglob ~14.5sec
iglob: ~16.9sec
The platform: Ubuntu 16.04, x86_64 (core i7),
Recently I had to recover my pictures with the extension .jpg. I ran photorec and recovered 4579 directories 2.2 million files within, having tremendous variety of extensions.With the script below I was able to select 50133 files havin .jpg extension within minutes:
#!/usr/binenv python2.7
import glob
import shutil
import os
src_dir = "/home/mustafa/Masaüstü/yedek"
dst_dir = "/home/mustafa/Genel/media"
for mediafile in glob.iglob(os.path.join(src_dir, "*", "*.jpg")): #"*" is for subdirectory
shutil.copy(mediafile, dst_dir)
based on other answers this is my current working implementation, which retrieves nested xml files in a root directory:
files = []
for root, dirnames, filenames in os.walk(myDir):
files.extend(glob.glob(root + "/*.xml"))
I'm really having fun with python :)
For python 3.5 and later
import glob
#file_names_array = glob.glob('path/*.c', recursive=True)
#above works for files directly at path/ as guided by NeStack
#updated version
file_names_array = glob.glob('path/**/*.c', recursive=True)
further you might need
for full_path_in_src in file_names_array:
print (full_path_in_src ) # be like 'abc/xyz.c'
#Full system path of this would be like => 'path till src/abc/xyz.c'
Johan and Bruno provide excellent solutions on the minimal requirement as stated. I have just released Formic which implements Ant FileSet and Globs which can handle this and more complicated scenarios. An implementation of your requirement is:
import formic
fileset = formic.FileSet(include="/src/**/*.c")
for file_name in fileset.qualified_files():
print file_name
Another way to do it using just the glob module. Just seed the rglob method with a starting base directory and a pattern to match and it will return a list of matching file names.
import glob
import os
def _getDirs(base):
return [x for x in glob.iglob(os.path.join( base, '*')) if os.path.isdir(x) ]
def rglob(base, pattern):
list = []
list.extend(glob.glob(os.path.join(base,pattern)))
dirs = _getDirs(base)
if len(dirs):
for d in dirs:
list.extend(rglob(os.path.join(base,d), pattern))
return list
Or with a list comprehension:
>>> base = r"c:\User\xtofl"
>>> binfiles = [ os.path.join(base,f)
for base, _, files in os.walk(root)
for f in files if f.endswith(".jpg") ]
If the files are on a remote file system or inside an archive, you can use an implementation of the fsspec AbstractFileSystem class. For example, to list all the files in a zipfile:
from fsspec.implementations.zip import ZipFileSystem
fs = ZipFileSystem("/tmp/test.zip")
fs.glob("/**") # equivalent: fs.find("/")
or to list all the files in a publicly available S3 bucket:
from s3fs import S3FileSystem
fs_s3 = S3FileSystem(anon=True)
fs_s3.glob("noaa-goes16/ABI-L1b-RadF/2020/045/**") # or use fs_s3.find
you can also use it for a local filesystem, which may be interesting if your implementation should be filesystem-agnostic:
from fsspec.implementations.local import LocalFileSystem
fs = LocalFileSystem()
fs.glob("/tmp/test/**")
Other implementations include Google Cloud, Github, SFTP/SSH, Dropbox, and Azure. For details, see the fsspec API documentation.
Just made this.. it will print files and directory in hierarchical way
But I didn't used fnmatch or walk
#!/usr/bin/python
import os,glob,sys
def dirlist(path, c = 1):
for i in glob.glob(os.path.join(path, "*")):
if os.path.isfile(i):
filepath, filename = os.path.split(i)
print '----' *c + filename
elif os.path.isdir(i):
dirname = os.path.basename(i)
print '----' *c + dirname
c+=1
dirlist(i,c)
c-=1
path = os.path.normpath(sys.argv[1])
print(os.path.basename(path))
dirlist(path)
That one uses fnmatch or regular expression:
import fnmatch, os
def filepaths(directory, pattern):
for root, dirs, files in os.walk(directory):
for basename in files:
try:
matched = pattern.match(basename)
except AttributeError:
matched = fnmatch.fnmatch(basename, pattern)
if matched:
yield os.path.join(root, basename)
# usage
if __name__ == '__main__':
from pprint import pprint as pp
import re
path = r'/Users/hipertracker/app/myapp'
pp([x for x in filepaths(path, re.compile(r'.*\.py$'))])
pp([x for x in filepaths(path, '*.py')])
In addition to the suggested answers, you can do this with some lazy generation and list comprehension magic:
import os, glob, itertools
results = itertools.chain.from_iterable(glob.iglob(os.path.join(root,'*.c'))
for root, dirs, files in os.walk('src'))
for f in results: print(f)
Besides fitting in one line and avoiding unnecessary lists in memory, this also has the nice side effect, that you can use it in a way similar to the ** operator, e.g., you could use os.path.join(root, 'some/path/*.c') in order to get all .c files in all sub directories of src that have this structure.
This is a working code on Python 2.7. As part of my devops work, I was required to write a script which would move the config files marked with live-appName.properties to appName.properties. There could be other extension files as well like live-appName.xml.
Below is a working code for this, which finds the files in the given directories (nested level) and then renames (moves) it to the required filename
def flipProperties(searchDir):
print "Flipping properties to point to live DB"
for root, dirnames, filenames in os.walk(searchDir):
for filename in fnmatch.filter(filenames, 'live-*.*'):
targetFileName = os.path.join(root, filename.split("live-")[1])
print "File "+ os.path.join(root, filename) + "will be moved to " + targetFileName
shutil.move(os.path.join(root, filename), targetFileName)
This function is called from a main script
flipProperties(searchDir)
Hope this helps someone struggling with similar issues.
Simplified version of Johan Dahlin's answer, without fnmatch.
import os
matches = []
for root, dirnames, filenames in os.walk('src'):
matches += [os.path.join(root, f) for f in filenames if f[-2:] == '.c']
Here is my solution using list comprehension to search for multiple file extensions recursively in a directory and all subdirectories:
import os, glob
def _globrec(path, *exts):
""" Glob recursively a directory and all subdirectories for multiple file extensions
Note: Glob is case-insensitive, i. e. for '\*.jpg' you will get files ending
with .jpg and .JPG
Parameters
----------
path : str
A directory name
exts : tuple
File extensions to glob for
Returns
-------
files : list
list of files matching extensions in exts in path and subfolders
"""
dirs = [a[0] for a in os.walk(path)]
f_filter = [d+e for d in dirs for e in exts]
return [f for files in [glob.iglob(files) for files in f_filter] for f in files]
my_pictures = _globrec(r'C:\Temp', '\*.jpg','\*.bmp','\*.png','\*.gif')
for f in my_pictures:
print f
import sys, os, glob
dir_list = ["c:\\books\\heap"]
while len(dir_list) > 0:
cur_dir = dir_list[0]
del dir_list[0]
list_of_files = glob.glob(cur_dir+'\\*')
for book in list_of_files:
if os.path.isfile(book):
print(book)
else:
dir_list.append(book)
I modified the top answer in this posting.. and recently created this script which will loop through all files in a given directory (searchdir) and the sub-directories under it... and prints filename, rootdir, modified/creation date, and size.
Hope this helps someone... and they can walk the directory and get fileinfo.
import time
import fnmatch
import os
def fileinfo(file):
filename = os.path.basename(file)
rootdir = os.path.dirname(file)
lastmod = time.ctime(os.path.getmtime(file))
creation = time.ctime(os.path.getctime(file))
filesize = os.path.getsize(file)
print "%s**\t%s\t%s\t%s\t%s" % (rootdir, filename, lastmod, creation, filesize)
searchdir = r'D:\Your\Directory\Root'
matches = []
for root, dirnames, filenames in os.walk(searchdir):
## for filename in fnmatch.filter(filenames, '*.c'):
for filename in filenames:
## matches.append(os.path.join(root, filename))
##print matches
fileinfo(os.path.join(root, filename))
Here is a solution that will match the pattern against the full path and not just the base filename.
It uses fnmatch.translate to convert a glob-style pattern into a regular expression, which is then matched against the full path of each file found while walking the directory.
re.IGNORECASE is optional, but desirable on Windows since the file system itself is not case-sensitive. (I didn't bother compiling the regex because docs indicate it should be cached internally.)
import fnmatch
import os
import re
def findfiles(dir, pattern):
patternregex = fnmatch.translate(pattern)
for root, dirs, files in os.walk(dir):
for basename in files:
filename = os.path.join(root, basename)
if re.search(patternregex, filename, re.IGNORECASE):
yield filename
I needed a solution for python 2.x that works fast on large directories.
I endet up with this:
import subprocess
foundfiles= subprocess.check_output("ls src/*.c src/**/*.c", shell=True)
for foundfile in foundfiles.splitlines():
print foundfile
Note that you might need some exception handling in case ls doesn't find any matching file.
I have the following directory structure:
-mailDir
-folderA
-sub1
-sub2
-inbox
-1.txt
-2.txt
-89.txt
-subInbox
-subInbox2
-folderB
-sub1
-sub2
-inbox
-1.txt
-2.txt
-200.txt
-577.txt
The aim is to copy all the txt files under inbox folder into another folder.
For this I tried the below code
import os
from os import path
import shutil
rootDir = "mailDir"
destDir = "destFolder"
eachInboxFolderPath = []
for root, dirs, files in os.walk(rootDir):
for dirName in dirs:
if(dirName=="inbox"):
eachInboxFolderPath.append(root+"\\"+dirName)
for ii in eachInboxFolderPath:
for i in os.listdir(ii):
shutil.copy(path.join(ii,i),destDir)
If the inbox directory only has .txt files then the above code works fine. Since the inbox folder under folderA directory has other sub directory along with .txt files, the code returns permission denied error. What I understood is shutil.copy won't allow to copy the folders.
The aim is to copy only the txt files in every inbox folder to some other location. If the file names are same in different inbox folder I have to keep both file names. How we can improve the code in this case ? Please note other than .txt all others are folders only.
One simple solution is to filter for any i that does not have the .txt extension by using the string endswith() method.
import os
from os import path
import shutil
rootDir = "mailDir"
destDir = "destFolder"
eachInboxFolderPath = []
for root, dirs, files in os.walk(rootDir):
for dirName in dirs:
if(dirName=="inbox"):
eachInboxFolderPath.append(root+"\\"+dirName)
for ii in eachInboxFolderPath:
for i in os.listdir(ii):
if i.endswith('.txt'):
shutil.copy(path.join(ii,i),destDir)
This should ignore any folders and non-txt files that are found with os.listdir(ii). I believe that is what you are looking for.
Just remembered that I once wrote several files to solve this exact problem before. You can find the source code here on my Github.
In short, there are two functions of interest here:
list_files(loc, return_dirs=False, return_files=True, recursive=False, valid_exts=None)
copy_files(loc, dest, rename=False)
For your case, you could copy and paste these functions into your project and modify copy_files like this:
def copy_files(loc, dest, rename=False):
# get files with full path
files = list_files(loc, return_dirs=False, return_files=True, recursive=True, valid_exts=('.txt',))
# copy files in list to dest
for i, this_file in enumerate(files):
# change name if renaming
if rename:
# replace slashes with hyphens to preserve unique name
out_file = sub(r'^./', '', this_file)
out_file = sub(r'\\|/', '-', out_file)
out_file = join(dest, out_file)
copy(this_file, out_file)
files[i] = out_file
else:
copy(this_file, dest)
return files
Then just call it like so:
copy_files('mailDir', 'destFolder', rename=True)
The renaming scheme might not be exactly what you want, but it will at least not override your files. I believe this should solve all your problems.
Here you go:
import os
from os import path
import shutil
destDir = '<absolute-path>'
for root, dirs, files in os.walk(os.getcwd()):
# Filter out only '.txt' files.
files = [f for f in files if f.endswith('.txt')]
# Filter out only 'inbox' directory.
dirs[:] = [d for d in dirs if d == 'inbox']
for f in files:
p = path.join(root, f)
# print p
shutil.copy(p, destDir)
Quick and simple.
sorry, I forgot the part where, you also need unique file names as well. The above solution only works for distinct file names in a single inbox folder.
For copying files from multiple inboxes and having a unique name in the destination folder, you can try this:
import os
from os import path
import shutil
sourceDir = os.getcwd()
fixedLength = len(sourceDir)
destDir = '<absolute-path>'
filteredFiles = []
for root, dirs, files in os.walk(sourceDir):
# Filter out only '.txt' files in all the inbox directories.
if root.endswith('inbox'):
# here I am joining the file name to the full path while filtering txt files
files = [path.join(root, f) for f in files if f.endswith('.txt')]
# add the filtered files to the main list
filteredFiles.extend(files)
# making a tuple of file path and file name
filteredFiles = [(f, f[fixedLength+1:].replace('/', '-')) for f in filteredFiles]
for (f, n) in filteredFiles:
print 'copying file...', f
# copying from the path to the dest directory with specific name
shutil.copy(f, path.join(destDir, n))
print 'copied', str(len(filteredFiles)), 'files to', destDir
If you need to copy all files instead of just txt files, then just change the condition f.endswith('.txt') to os.path.isfile(f) while filtering out the files.
This is what I have:
glob(os.path.join('src','*.c'))
but I want to search the subfolders of src. Something like this would work:
glob(os.path.join('src','*.c'))
glob(os.path.join('src','*','*.c'))
glob(os.path.join('src','*','*','*.c'))
glob(os.path.join('src','*','*','*','*.c'))
But this is obviously limited and clunky.

rglob ~14.5sec
iglob: ~16.9sec
The platform: Ubuntu 16.04, x86_64 (core i7),
Recently I had to recover my pictures with the extension .jpg. I ran photorec and recovered 4579 directories 2.2 million files within, having tremendous variety of extensions.With the script below I was able to select 50133 files havin .jpg extension within minutes:
#!/usr/binenv python2.7
import glob
import shutil
import os
src_dir = "/home/mustafa/Masaüstü/yedek"
dst_dir = "/home/mustafa/Genel/media"
for mediafile in glob.iglob(os.path.join(src_dir, "*", "*.jpg")): #"*" is for subdirectory
shutil.copy(mediafile, dst_dir)
based on other answers this is my current working implementation, which retrieves nested xml files in a root directory:
files = []
for root, dirnames, filenames in os.walk(myDir):
files.extend(glob.glob(root + "/*.xml"))
I'm really having fun with python :)
For python 3.5 and later
import glob
#file_names_array = glob.glob('path/*.c', recursive=True)
#above works for files directly at path/ as guided by NeStack
#updated version
file_names_array = glob.glob('path/**/*.c', recursive=True)
further you might need
for full_path_in_src in file_names_array:
print (full_path_in_src ) # be like 'abc/xyz.c'
#Full system path of this would be like => 'path till src/abc/xyz.c'
Johan and Bruno provide excellent solutions on the minimal requirement as stated. I have just released Formic which implements Ant FileSet and Globs which can handle this and more complicated scenarios. An implementation of your requirement is:
import formic
fileset = formic.FileSet(include="/src/**/*.c")
for file_name in fileset.qualified_files():
print file_name
Another way to do it using just the glob module. Just seed the rglob method with a starting base directory and a pattern to match and it will return a list of matching file names.
import glob
import os
def _getDirs(base):
return [x for x in glob.iglob(os.path.join( base, '*')) if os.path.isdir(x) ]
def rglob(base, pattern):
list = []
list.extend(glob.glob(os.path.join(base,pattern)))
dirs = _getDirs(base)
if len(dirs):
for d in dirs:
list.extend(rglob(os.path.join(base,d), pattern))
return list
Or with a list comprehension:
>>> base = r"c:\User\xtofl"
>>> binfiles = [ os.path.join(base,f)
for base, _, files in os.walk(root)
for f in files if f.endswith(".jpg") ]
If the files are on a remote file system or inside an archive, you can use an implementation of the fsspec AbstractFileSystem class. For example, to list all the files in a zipfile:
from fsspec.implementations.zip import ZipFileSystem
fs = ZipFileSystem("/tmp/test.zip")
fs.glob("/**") # equivalent: fs.find("/")
or to list all the files in a publicly available S3 bucket:
from s3fs import S3FileSystem
fs_s3 = S3FileSystem(anon=True)
fs_s3.glob("noaa-goes16/ABI-L1b-RadF/2020/045/**") # or use fs_s3.find
you can also use it for a local filesystem, which may be interesting if your implementation should be filesystem-agnostic:
from fsspec.implementations.local import LocalFileSystem
fs = LocalFileSystem()
fs.glob("/tmp/test/**")
Other implementations include Google Cloud, Github, SFTP/SSH, Dropbox, and Azure. For details, see the fsspec API documentation.
Just made this.. it will print files and directory in hierarchical way
But I didn't used fnmatch or walk
#!/usr/bin/python
import os,glob,sys
def dirlist(path, c = 1):
for i in glob.glob(os.path.join(path, "*")):
if os.path.isfile(i):
filepath, filename = os.path.split(i)
print '----' *c + filename
elif os.path.isdir(i):
dirname = os.path.basename(i)
print '----' *c + dirname
c+=1
dirlist(i,c)
c-=1
path = os.path.normpath(sys.argv[1])
print(os.path.basename(path))
dirlist(path)
That one uses fnmatch or regular expression:
import fnmatch, os
def filepaths(directory, pattern):
for root, dirs, files in os.walk(directory):
for basename in files:
try:
matched = pattern.match(basename)
except AttributeError:
matched = fnmatch.fnmatch(basename, pattern)
if matched:
yield os.path.join(root, basename)
# usage
if __name__ == '__main__':
from pprint import pprint as pp
import re
path = r'/Users/hipertracker/app/myapp'
pp([x for x in filepaths(path, re.compile(r'.*\.py$'))])
pp([x for x in filepaths(path, '*.py')])
In addition to the suggested answers, you can do this with some lazy generation and list comprehension magic:
import os, glob, itertools
results = itertools.chain.from_iterable(glob.iglob(os.path.join(root,'*.c'))
for root, dirs, files in os.walk('src'))
for f in results: print(f)
Besides fitting in one line and avoiding unnecessary lists in memory, this also has the nice side effect, that you can use it in a way similar to the ** operator, e.g., you could use os.path.join(root, 'some/path/*.c') in order to get all .c files in all sub directories of src that have this structure.
This is a working code on Python 2.7. As part of my devops work, I was required to write a script which would move the config files marked with live-appName.properties to appName.properties. There could be other extension files as well like live-appName.xml.
Below is a working code for this, which finds the files in the given directories (nested level) and then renames (moves) it to the required filename
def flipProperties(searchDir):
print "Flipping properties to point to live DB"
for root, dirnames, filenames in os.walk(searchDir):
for filename in fnmatch.filter(filenames, 'live-*.*'):
targetFileName = os.path.join(root, filename.split("live-")[1])
print "File "+ os.path.join(root, filename) + "will be moved to " + targetFileName
shutil.move(os.path.join(root, filename), targetFileName)
This function is called from a main script
flipProperties(searchDir)
Hope this helps someone struggling with similar issues.
Simplified version of Johan Dahlin's answer, without fnmatch.
import os
matches = []
for root, dirnames, filenames in os.walk('src'):
matches += [os.path.join(root, f) for f in filenames if f[-2:] == '.c']
Here is my solution using list comprehension to search for multiple file extensions recursively in a directory and all subdirectories:
import os, glob
def _globrec(path, *exts):
""" Glob recursively a directory and all subdirectories for multiple file extensions
Note: Glob is case-insensitive, i. e. for '\*.jpg' you will get files ending
with .jpg and .JPG
Parameters
----------
path : str
A directory name
exts : tuple
File extensions to glob for
Returns
-------
files : list
list of files matching extensions in exts in path and subfolders
"""
dirs = [a[0] for a in os.walk(path)]
f_filter = [d+e for d in dirs for e in exts]
return [f for files in [glob.iglob(files) for files in f_filter] for f in files]
my_pictures = _globrec(r'C:\Temp', '\*.jpg','\*.bmp','\*.png','\*.gif')
for f in my_pictures:
print f
import sys, os, glob
dir_list = ["c:\\books\\heap"]
while len(dir_list) > 0:
cur_dir = dir_list[0]
del dir_list[0]
list_of_files = glob.glob(cur_dir+'\\*')
for book in list_of_files:
if os.path.isfile(book):
print(book)
else:
dir_list.append(book)
I modified the top answer in this posting.. and recently created this script which will loop through all files in a given directory (searchdir) and the sub-directories under it... and prints filename, rootdir, modified/creation date, and size.
Hope this helps someone... and they can walk the directory and get fileinfo.
import time
import fnmatch
import os
def fileinfo(file):
filename = os.path.basename(file)
rootdir = os.path.dirname(file)
lastmod = time.ctime(os.path.getmtime(file))
creation = time.ctime(os.path.getctime(file))
filesize = os.path.getsize(file)
print "%s**\t%s\t%s\t%s\t%s" % (rootdir, filename, lastmod, creation, filesize)
searchdir = r'D:\Your\Directory\Root'
matches = []
for root, dirnames, filenames in os.walk(searchdir):
## for filename in fnmatch.filter(filenames, '*.c'):
for filename in filenames:
## matches.append(os.path.join(root, filename))
##print matches
fileinfo(os.path.join(root, filename))
Here is a solution that will match the pattern against the full path and not just the base filename.
It uses fnmatch.translate to convert a glob-style pattern into a regular expression, which is then matched against the full path of each file found while walking the directory.
re.IGNORECASE is optional, but desirable on Windows since the file system itself is not case-sensitive. (I didn't bother compiling the regex because docs indicate it should be cached internally.)
import fnmatch
import os
import re
def findfiles(dir, pattern):
patternregex = fnmatch.translate(pattern)
for root, dirs, files in os.walk(dir):
for basename in files:
filename = os.path.join(root, basename)
if re.search(patternregex, filename, re.IGNORECASE):
yield filename
I needed a solution for python 2.x that works fast on large directories.
I endet up with this:
import subprocess
foundfiles= subprocess.check_output("ls src/*.c src/**/*.c", shell=True)
for foundfile in foundfiles.splitlines():
print foundfile
Note that you might need some exception handling in case ls doesn't find any matching file.
I would like to find all the files in a directory and all sub-directories.
code used:
import os
import sys
path = "C:\\"
dirs = os.listdir(path)
filename = "C.txt"
FILE = open(filename, "w")
FILE.write(str(dirs))
FILE.close()
print dirs
The problem is - this code only lists files in directories, not sub-directories. What do I need to change in order to also list files in subdirectories?
To traverse a directory tree you want to use os.walk() for this.
Here's an example to get you started:
import os
searchdir = r'C:\root_dir' # traversal starts in this directory (the root)
for root, dirs, files in os.walk(searchdir):
for name in files:
(base, ext) = os.path.splitext(name) # split base and extension
print base, ext
which would give you access to the file names and the components.
You'll find the functions in the os and os.path module to be of great use for this sort of work.
This function will help you: os.path.walk() http://docs.python.org/library/os.path.html#os.path.walk
How can I find all files in directory with the extension .csv in python?
import os
import glob
path = 'c:\\'
extension = 'csv'
os.chdir(path)
result = glob.glob('*.{}'.format(extension))
print(result)
from os import listdir
def find_csv_filenames( path_to_dir, suffix=".csv" ):
filenames = listdir(path_to_dir)
return [ filename for filename in filenames if filename.endswith( suffix ) ]
The function find_csv_filenames() returns a list of filenames as strings, that reside in the directory path_to_dir with the given suffix (by default, ".csv").
Addendum
How to print the filenames:
filenames = find_csv_filenames("my/directory")
for name in filenames:
print name
By using the combination of filters and lambda, you can easily filter out csv files in given folder.
import os
all_files = os.listdir("/path-to-dir")
csv_files = list(filter(lambda f: f.endswith('.csv'), all_files))
# lambda returns True if filename (within `all_files`) ends with .csv or else False
# and filter function uses the returned boolean value to filter .csv files from list files.
use Python OS module to find csv file in a directory.
the simple example is here :
import os
# This is the path where you want to search
path = r'd:'
# this is the extension you want to detect
extension = '.csv'
for root, dirs_list, files_list in os.walk(path):
for file_name in files_list:
if os.path.splitext(file_name)[-1] == extension:
file_name_path = os.path.join(root, file_name)
print file_name
print file_name_path # This is the full path of the filter file
I had to get csv files that were in subdirectories, therefore, using the response from tchlpr I modified it to work best for my use case:
import os
import glob
os.chdir( '/path/to/main/dir' )
result = glob.glob( '*/**.csv' )
print( result )
import os
path = 'C:/Users/Shashank/Desktop/'
os.chdir(path)
for p,n,f in os.walk(os.getcwd()):
for a in f:
a = str(a)
if a.endswith('.csv'):
print(a)
print(p)
This will help to identify path also of these csv files
While solution given by thclpr works it scans only immediate files in the directory and not files in the sub directories if any. Although this is not the requirement but just in case someone wishes to scan sub directories too below is the code that uses os.walk
import os
from glob import glob
PATH = "/home/someuser/projects/someproject"
EXT = "*.csv"
all_csv_files = [file
for path, subdir, files in os.walk(PATH)
for file in glob(os.path.join(path, EXT))]
print(all_csv_files)
Copied from this blog.
Use the python glob module to easily list out the files we need.
import glob
path_csv=glob.glob("../data/subfolrder/*.csv")
You could just use glob with recursive = true, the pattern ** will match any files and zero or more directories, subdirectories and symbolic links to directories.
import glob, os
os.chdir("C:\\Users\\username\\Desktop\\MAIN_DIRECTORY")
for file in glob.glob("*/.csv", recursive = true):
print(file)
This solution uses the python function filter. This function creates a list of elements for which a function returns true. In this case, the anonymous function used is partial matching '.csv' on every element of the directory files list obtained with os.listdir('the path i want to look in')
import os
filepath= 'filepath_to_my_CSVs' # for example: './my_data/'
list(filter(lambda x: '.csv' in x, os.listdir('filepath_to_my_CSVs')))
Many (linked) answers change working directory with os.chdir(). But you don't have to.
Recursively print all CSV files in /home/project/ directory:
pathname = "/home/project/**/*.csv"
for file in glob.iglob(pathname, recursive=True):
print(file)
Requires python 3.5+. From docs [1]:
pathname can be either absolute (like /usr/src/Python-1.5/Makefile) or relative (like ../../Tools/*/*.gif)
pathname can contain shell-style wildcards.
Whether or not the results are sorted depends on the file system.
If recursive is true, the pattern ** will match any files and zero or more directories, subdirectories and symbolic links to directories
[1] https://docs.python.org/3/library/glob.html#glob.glob
You could just use glob with recursive = True, the pattern ** will match any files and zero or more directories, subdirectories and symbolic links to directories.
import glob, os
os.chdir("C:\\Users\\username\\Desktop\\MAIN_DIRECTORY")
for file in glob.glob("*/*.csv", recursive = True):
print(file)
Please use this tested working code. This function will return a list of all the CSV files with absolute CSV file paths in your specified path.
import os
from glob import glob
def get_csv_files(dir_path, ext):
os.chdir(dir_path)
return list(map(lambda x: os.path.join(dir_path, x), glob(f'*.{ext}')))
print(get_csv_files("E:\\input\\dir\\path", "csv"))
