Checking Path Existence and Permissions

Perform checks using os.access

os.access is much better solution to check whether directory exists and it’s accesable 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 Wriable
os.access(path, os.W_OK)

## Check if path is Execuatble
os.access(path, os.E_OK)

also it’s possible to perfrom 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.

Parameters

|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.
