Python Forum

Hello!
So i have been working with python on Ubuntu which i boot from a pendrive on a computer whose hard disk is corrupted. I had taken the pen-drive off the computer while it was in sleep mode, used the pendrive on another computer and then plugged it back in to the sleeping computer. Just for fun, i thought i'll run it like that. BIG MISTAKE!
Now, even writing

import requests

gives me an error like this:

Error:>>> import requests
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/bunni/.local/lib/python3.6/site-packages/requests/__init__.py", line 43, in <module>
    import urllib3
  File "/home/bunni/.local/lib/python3.6/site-packages/urllib3/__init__.py", line 8, in <module>
    from .connectionpool import (
  File "/home/bunni/.local/lib/python3.6/site-packages/urllib3/connectionpool.py", line 36, in <module>
    from .response import HTTPResponse
ValueError: source code string cannot contain null bytes

I tried uninstalling and reinstalling it using pip3, but it wont work either, and shows a similar error. This is not just with requests. even selenium doesnt work now.

All my files are preserved. No problems there, but no code is running.

Please advise what i can do to fix this problem

This is extremely weird.

import selenium

itself doesnt return any error, but

from selenium import webdriver

returns the following error:

Error:from selenium import webdriver

It looks like only one file is not working properly...Any inputs on how to locate and fix it?

EDIT:
I'm able to import os, time, shutil, pprint, bs4, openpyxl normally.

Okay, so i followed the path in the traceback and found the corrupted file. Then replaced it with the file with the same name on GitHub. Now its working :)

Update:
The response file is fine now, but the socks file in contribs is showing the same error, and it is not resolving on doing what i did to correct the response file.
This is the error i get:

Error:Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Any help will be greatly appreciated!

okay, deleting the entire urllib3 folder from the path and reinstalling it worked for me.
