这里有一个解决方案。未经测试！

请注意使用os.walk()就地更改dirnames的能力，告诉它不要递归到子目录中，并且避免使用{}，这会破坏此功能：When topdown is True, the caller can modify the dirnames list in-place

(perhaps using del or slice assignment), and walk() will only recurse

into the subdirectories whose names remain in dirnames; this can be

used to prune the search, [...]

Modifying dirnames when topdown is False has no effect on the behavior of the walk, because in bottom-up mode the directories in dirnames are generated before dirpath itself is generated.

有关详细信息，请参见the docs。在

同样值得注意的是使用os.path.samefile()进行路径比较。这是available on Windows since version 3.2。在

这是未经测试的！

使用风险自负！！

说真的，小心点！！！import os
