List of pathlib.Paths Not Ordered As Same List of Same String Filenames

[DeaD_EyE]

Please look into the source code. Github makes it very easy for us.

The bult-in function sorted calls __lt__ (means less then) of an object.
So we should look into the pathlib module and seek for __lt__

It's hard to follow the code, because there is heavy inheritance and some other patterns.
You should know that pathobject._cparts returns a list spitted by it's parts. A path separator is also a part, if it's the root directory (absolute path).

Comparing lists in Python does not do what you think it should do. It compares in lexicographical order. I got this answer from here.

Comparing the paths as str:

'/spam/spams.txt' < '/spam/spams/spam04.doc'

Output:
True

Comparing the _cparts:

['/', 'spam', 'spams.txt'] < ['/', 'spam', 'spams', 'spam04.doc']

Output:
False

Index 0 and 1 are identical. Index 3 is bigger than index 3 from the other list. Then there are no more elements in the first list for comparison and the operation stops and yields the last result, which is False.

'spams.txt' < 'spam04.doc'

In simple words: Paths are sorted in alphabetical order by their elements.
