I am having trouble trying to save a dictionary using pickle in python:
my code is the following:
import re
import os
def save_obj(outputFolder,obj, name ):
directory = outputFolder + ' obj/'
if not os.path.exists(directory):
os.makedirs(directory)
with open(directory + name + '.pkl', 'wb') as f:
pickle.dump(obj, f, pickle.HIGHEST_PROTOCOL)
The Error message is the following:
File "CleanPEPS.py", line 14, in save_obj
pickle.dump(obj, f, pickle.HIGHEST_PROTOCOL)
NameError: name 'pickle' is not defined
It is a problem of library or something like that? Or there is something that I have forgotten?
You're missing import pickle. Other than that your code looks OK. If you have any more issues check out the pickle docs.

good afternoon!
saving list(dict(),dict(),dict()) struct with pickle module, but when reading I get: <class 'function'>, and <function lesson at 0x00000278BA3A0D30>
what am I doing wrong?
def lesson(user, date):
with open(user+"_"+date+".data", 'wb') as file:
pickle.dump(lesson, file)
file.close()
def read(user, date):
with open(user+"_"+date+".data", 'rb') as file:
lesson = pickle.load(file)
file.close()
return(lesson)
I am using python 3.10.7
"saving list(dict(),dict(),dict()) struct with pickle module". No, you're not. You're saving the lesson function. See line 3 of your code.
I am trying to write to a .txt file and then copy it into a second .txt file.
from sys import argv
script, send_file, get_file = argv
in_file = open(send_file, "r+")
in_file.write("I'm sending information to the receiver file.")
open(get_file, "w")
get_file.write(f"{in_file}")
But I keep getting the same error:
Traceback (most recent call last):
File "ex15_test.py", line 11, in <module>
get_file.write(f"{in_file}")
AttributeError: 'str' object has no attribute 'write'
Then I put open(get_file, "w") and get_file.write(f"{in_file}") inside of a variable and get no error whatsoever.
out_file = open(get_file, "w")
out_file.write(f"{in_file}")
But then this is what ends up being written into the second file:
<_io.TextIOWrapper name='sender.txt' mode='r+' encoding='cp1252'>
Do you know what I'm doing wrong?
Why did it work when I used the variables in the second code?
In open(get_file, "w"), get_file is the name of the file, it's a string.
You need to write to a file object, as you did to read in the first part of the code. So, it would be:
f = open(get_file, "w")
f.write(f"{in_file}")
f.close()
Note that you forgot to close both of your files in your code.
The good practice, though, is to use a context manager that will take care of the closing for you, whatever happens in your code (exception, ...)
So, the best way to do it would be:
with open(get_file, "w") as f:
f.write(f"{in_file}")
Sorry for messy code but this should do what you want i think
from sys import argv
script, send_file, get_file = argv
in_file = open(send_file, "r+")
in_file.write("I'm sending information to the receiver file.")
in_file.close()
in_file_2 = open(send_file, "r")
in_file_text = in_file_2.read()
in_file_2.close()
secondFile = open(get_file, "w")
secondFile.write(f"{in_file_text}")
secondFile.close()
I would like to convert a large batch of MS Word files into the plain text format. I have no idea how to do it in Python. I found the following code online. My path is local and all file names are like cx-xxx (i.e. c1-000, c1-001, c2-000, c2-001 etc.):
from docx import [name of file]
import io
import shutil
import os
def convertDocxToText(path):
for d in os.listdir(path):
fileExtension=d.split(".")[-1]
if fileExtension =="docx":
docxFilename = path + d
print(docxFilename)
document = Document(docxFilename)
textFilename = path + d.split(".")[0] + ".txt"
with io.open(textFilename,"c", encoding="utf-8") as textFile:
for para in document.paragraphs:
textFile.write(unicode(para.text))
path= "/home/python/resumes/"
convertDocxToText(path)
Convert docx to txt with pypandoc:
import pypandoc
# Example file:
docxFilename = 'somefile.docx'
output = pypandoc.convert_file(docxFilename, 'plain', outputfile="somefile.txt")
assert output == ""
See the official documentation here:
https://pypi.org/project/pypandoc/
You can also use the library docx2txt in Python. Here's an example:
I use glob to iter over all DOCX files in the folder.
Note: I use a little list comprehension on the original name in order to re-use it in the TXT filename.
If there's anything I've forgotten to explain, tag me and I'll edit it in.
import docx2txt
import glob
directory = glob.glob('C:/folder_name/*.docx')
for file_name in directory:
with open(file_name, 'rb') as infile:
outfile = open(file_name[:-5]+'.txt', 'w', encoding='utf-8')
doc = docx2txt.process(infile)
outfile.write(doc)
outfile.close()
infile.close()
print("=========")
print("All done!")`
GroupDocs.Conversion Cloud SDK for Python supports 50+ file formats conversion. Its free plan provides 150 free API calls monthly.

I am having trouble creating and writing to a text file in Python. I am running Python 3.5.1 and have the following code to try and create and write to a file:
from os import *
custom_path = "MyDirectory/"
if not path.exists(custom_path)
mkdir(custom_path)
text_path = custom_path + "MyTextFile.txt"
text_file = open(text_path, "w")
text_file.write("my text")
But I get a TypeError saying an integer is required (got type str) at the line text_file = open(text_path, "w").
I don't know what I'm doing wrong as my code is just about identical to that of several tutorial sites showing how to create and write to files.
Also, does the above code create the text file if it doesn't exist, and if not how do I create it?
Please don't import everything from os module:
from os import path, mkdir
custom_path = "MyDirectory/"
if not path.exists(custom_path):
mkdir(custom_path)
text_path = custom_path + "MyTextFile.txt"
text_file = open(text_path, 'w')
text_file.write("my text")
Because there also a "open" method in os module which will overwrite the native file "open" method.
I am running Python 3.x. So i have been working on some code for fetching data on currencies names around the world from a currency website to get information which the code is as follows
def _fetch_currencies():
import urllib.request
import json
f = urllib.request.urlopen('http://openexchangerates.org/api/currencies.json')
charset = f.info().get_param('charset', 'utf8')
data = f.read()
decoded = json.loads(data.decode(charset))
dumps = json.dumps(decoded, indent=4)
return dumps
I then need to save it as a file locally but having some issue and cant see where.
Here is the code for saving the currencies:
def save_currencies(_fetch_currencies, filename):
sorted_currencies = sorted(decoded.items())
with open(filename, 'w') as my_csv:
csv_writer = csv.writer(my_csv, delimiter=',')
csv_writer.writerows(sorted_currencies)
They just don't seem to work together apart from when i remove the line ' dumps = json.dumps(decoded, indent=4) ' but i need that line to be able to print the file in text, how do i get around deleting this line and still be able to save and print? How do i also pick where it saves?
Any Help will be great, thank you very much anyone and everyone who answers/reads this.
I may be mistaken, but your "decoded" variable should be declared as global in both functions.
I would actually have _fetch_currencies() return a dictionary, and then I would pass that dictionary on to saved_currencies(currencies_decoded, filename). For example:
def _fetch_currencies():
import urllib.request
import json
f = urllib.request.urlopen('http://openexchangerates.org/api/currencies.json')
charset = f.info().get_param('charset', 'utf8')
data = f.read()
decoded = json.loads(data.decode(charset))
return decoded
def save_currencies(currencies_decoded, filename):
sorted_currencies = sorted(currencies_decoded.items())
with open(filename, 'w') as my_csv:
csv_writer = csv.writer(my_csv, delimiter=',')
csv_writer.writerows(sorted_currencies)
my_currencies_decoded = _fetch_currencies()
save_currencies(my_currencies_decoded, "filename.csv")
Furthermore, if you would like to save your csv file to a certain location in your filesystem, you can import os and use the os.path.join() function and provide it the FULL path. For example, to save your .csv file to a location called "/Documents/Location/Here", you can do:
import os
def save_currencies(currencies_decoded, filename):
sorted_currencies = sorted(currencies_decoded.items())
with open(os.path.join("Documents","Location","Here"), 'w') as my_csv:
csv_writer = csv.writer(my_csv, delimiter=',')
csv_writer.writerows(sorted_currencies)
You can also use a relative path, so that if you're already in directory "Documents", and you'd like to save a file in "/Documents/Location/Here", you can instead just say:
with open(os.path.join("Location", "Here"), 'w') as my_csv:
