python - 在python中查找所有linux文件的总目录

Question

我想在 python 中找到所有 linux 文件的通用目录(不是目录)。大家能帮帮我吗？

示例 1:

['/home/tung/abc.txt', '/home/tung/xyz.txt']
    -> general directory: '/home/tung'

例子2:

['/home/tung/abc.txt', '/home/tung/xyz.txt', '/home/user/123.txt']
    -> general directory: '/home'

示例 3:

['/home/tung/abc.txt', '/root/xyz.txt']
    -> general directory: '/'

Answer 1

os.path.commonprefix(list)

Return the longest path prefix (taken character-by-character) that is a prefix of all paths in list. If list is empty, return the empty string (''). Note that this may return invalid paths because it works a character at a time.

或者，如果您使用的是 python 3.4+(我想这部分答案更适合 future )，您可以使用 pathlib 和: PurePaths.parts会给你一个

tuple giving access to the path’s various components.

将不同文件的元组转换为列表，然后找到common list of prefixes for a list of lists .
