Checking Path Existence and Permissions

Checking Path Existence and Permissions

Parameter Details

os.F_OK Value to pass as the mode parameter of access() to test the existence of path.

os.R_OK Value to include in the mode parameter of access() to test the readability of path.

os.W_OK Value to include in the mode parameter of access() to test the writability of path.

os.X_OK Value to include in the mode parameter of access() to determine if path can be executed.

Perform checks using os.access

os.access is much better solution to check whether directory exists and it’s accessible for reading and writing.

import os
path = "/home/myFiles/directory1"
Check if path exists os.access(path, os.F_OK)
Check if path is Readable os.access(path, os.R_OK)
Check if path is Writable os.access(path, os.W_OK)
Check if path is Executable os.access(path, os.E_OK)
also it's possible to perform all checks together

os.access(path, os.F_OK & os.R_OK & os.W_OK & os.E_OK)

All the above returns True if access is allowed and False if not allowed. These are available on unix and windows.
