如何在python中找到文件或目录的所有者

Question

我需要Python中的函数或方法来查找文件或目录的所有者。

函数应该如下：

>>> find_owner("/home/somedir/somefile")
owner3

Answer 1

要使用^{}：

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)

获取所有者UID的用法示例：

from os import stat
stat(my_filename).st_uid

但是，请注意，stat返回的是用户id号（例如，0代表根），而不是实际的用户名。
