Get File's Permission Mask Using Python

To get stat of a file, method stat() from the os module can be used. It performs a stat system call on the given path. For example,

import os
st = os.stat("file.dat")

This function takes the name of a file, and returns a 10-member tuple with the following contents:

(mode, ino, dev, nlink, uid, gid, size, atime, mtime, ctime)

The mode variable gives you the information about file permissions. You can get it by st[0].
