Workarounds

  1. 90% success Check e.errno to determine the specific OS error code and handle accordingly 
    except OSError as e: if e.errno == errno.ENOSPC: ...
  2. 90% success Check file/directory permissions with os.access() before operations 
    os.access(path, os.R_OK | os.W_OK)

Dead Ends

Common approaches that don't work:

  1. Ignoring all OSError exceptions 80% fail

    System errors (disk full, permission denied) need proper handling
