Official Documentation

https://docs.python.org/3/library/exceptions.html

Workarounds

  1. 90% success Check file permissions with os.access() or ls -la 
    Use os.chmod() or chmod command to set correct permissions
  2. 90% success Check if the file is locked by another process or has read-only attribute 
    On Windows, use unlocker tool; on Linux, check lsof

Dead Ends

Common approaches that don't work:

  1. Running the script as root/Administrator 80% fail

    Security risk; underlying permission structure should be fixed instead
