我真的不太多蟒蛇的傢伙,但我能掀起這件事:

from os import stat 
from pwd import getpwuid 

def find_owner(filename): 
    return getpwuid(stat(filename).st_uid).pw_name

你想用os.stat()

os.stat(path) 
Perform the equivalent of a stat() system call on the given path. 
(This function follows symlinks; to stat a symlink use lstat().) 

The return value is an object whose attributes correspond to the 
members of the stat structure, namely: 

- st_mode - protection bits, 
- st_ino - inode number, 
- st_dev - device, 
- st_nlink - number of hard links, 
- st_uid - user id of owner, 
- st_gid - group id of owner, 
- st_size - size of file, in bytes, 
- st_atime - time of most recent access, 
- st_mtime - time of most recent content modification, 
- st_ctime - platform dependent; time of most recent metadata 
      change on Unix, or the time of creation on Windows) 

使用示例來獲得主UID:

from os import stat 
stat(my_filename).st_uid 

注意,但是, stat返回用戶標識號(例如,0代表根),而不是實際的用戶名。

請參閱os.stat。它給你st_uid這是所有者的用戶ID。然後你必須將其轉換爲名稱。要做到這一點,請使用pwd.getpwuid

下面是一些示例代碼,顯示你如何能找到文件的所有者:

#!/usr/bin/env python 
import os 
import pwd 
filename = '/etc/passwd' 
st = os.stat(filename) 
uid = st.st_uid 
print(uid) 
# output: 0 
userinfo = pwd.getpwuid(st.st_uid) 
print(userinfo) 
# output: pwd.struct_passwd(pw_name='root', pw_passwd='x', pw_uid=0, 
#   pw_gid=0, pw_gecos='root', pw_dir='/root', pw_shell='/bin/bash') 
ownername = pwd.getpwuid(st.st_uid).pw_name 
print(ownername) 
# output: root

我碰到這個偶然最近,希望得到所有人的用戶和組信息,所以我想我會分享我想出了:

import os 
from pwd import getpwuid 
from grp import getgrgid 

def get_file_ownership(filename): 
    return (
     getpwuid(os.stat(filename).st_uid).pw_name, 
     getgrgid(os.stat(filename).st_gid).gr_name 
    )
