如何在 Python 上使用 RE 获取 \ 字符右侧路径中的姓氏？

Question

I have been trying to make a good regular expression that catches the last name (of a file or folder) for a given path, meaning that for instance, the following path:

C:\Users\ResetStoreX\Pictures

Can be reduced to:

Pictures

What I have achieved so far is the following RE: (?:[^\\]\\)[^\\]*$

Which reduces the previous path to:

X\Pictures

Any ideas?

Answer 1

You almost had it. I removed the \ inside of the parentheses, if you want all backslashes to be captured.

(?:[^\\])[^\\]*$
