Python查找文件路径之间的差异

Question

我有一堆文件路径，比如：

path1 = "./base/folder1/subfolder"
path2 = "./base/folder2/"

我正在尝试编写一个可以为我提供路径之间相对差异的函数。使用上面的路径：

>>> get_path_difference(path1, path2)
"../../folder2"
>>> get_path_difference(path2, path1)
"../folder1/subfolder"

我查看了os.path 模块，因为这似乎应该是一种常见的事情，但要么我不知道术语，要么它不存在。

Answer 1

你可以使用os.path.relpath:

>>> path1 = "./base/folder1/subfolder"
>>> path2 = "./base/folder2/"
>>> import os
>>> os.path.relpath(path1, path2)
'../folder1/subfolder'
>>> os.path.relpath(path2, path1)
'../../folder2'

Answer 2

你想要os.path.relpath:

>>> import os
>>>
>>> path1 = "./base/folder1/subfolder"
>>> path2 = "./base/folder2/"
>>>
>>> os.path.relpath(path1, path2)
'../folder1/subfolder'
>>>
>>> os.path.relpath(path2, path1)
'../../folder2'
>>>
