Python找到文件路徑之間的差異

Question

我有一堆文件路徑，例如：

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

我正在嘗試編寫一個可以給我路徑之間相對差異的函數。 使用上面的路徑：

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

我已經瀏覽了os.path模塊，因為看起來這應該是常見的事情，但要么我不知道術語，要么它不存在。

Answer 1

您可以使用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'
>>>
