How to get the owner and group of a folder with Python on a Linux machine?

Question

How can I get the owner and group IDs of a directory using Python under Linux?

Solution 1

Use os.stat() to get the uid and gid of the file. Then, use pwd.getpwuid() and grp.getgrgid() to get the user and group names respectively.

import grp
import pwd
import os

stat_info = os.stat('/path')
uid = stat_info.st_uid
gid = stat_info.st_gid
print uid, gid

user = pwd.getpwuid(uid)[0]
group = grp.getgrgid(gid)[0]
print user, group

Solution 2

Since Python 3.4.4, the Path class of pathlib module provides a nice syntax for this:

from pathlib import Path
whatever = Path("relative/or/absolute/path/to_whatever")
if whatever.exists():
    print("Owner: %s" % whatever.owner())
    print("Group: %s" % whatever.group())

Solution 3

Use os.stat:

>>> s = os.stat('.')
>>> s.st_uid
1000
>>> s.st_gid
1000

st_uid is the user id of the owner, st_gid is the group id. See the linked documentation for other information that can be acuired through stat.
