permission change of files in python

Question

I want to change the file permission for all the files from my current directory tree. I am trying to open each directory and open the files and change the permission using os.chmod(), But getting an error.

import os
import stat

for files in os.walk('.'):
        os.chmod(files,stat.S_IXGRP)

The error I get is:

File "delhis.py", line 4, in ? os.chmod(files,stat.S_IXGRP) TypeError: coercing to Unicode: need string or buffer, tuple found

Answer 1

You are using os.walk incorrectly.

for dirpath, dirnames, filenames in os.walk('.'):
    for filename in filenames:
        path = os.path.join(dirpath, filename)
        os.chmod(path, 0o777) # for example

Answer 2

You can instead use an OS specific function call as follows:

os.system('chmod 777 -R *')
