How can I remove all write permissions from a directory with python recursivly

Question

I want to remove all write permissions from a directory and all it's sub-directories and files with python

I want something like this:

os.chmod(path, "a-w", recursive=True)

In bash it would be this:

chmod -R a-w $path

Answer 1

One way is to use subprocess module. Your code will look like that:

import subprocess

subprocess.call(['chmod', '-R', 'a-w', path])

For os-based solution see this answer.

Answer 2

import subprocess

try:
    subprocess.check_call(["chmod -R a-w {path}".format(path=path)], shell=True) # Or  subprocess.check_call(["chmod", "-R", "a-w", path])
except subprocess.CalledProcessError:
    pass # handle errors in the called executable
except OSError:
    pass # executable not found
