I have a string that has the path of the file stored in it.

path = \home\linux\testfile\abc\work

now I want to write a function with which I can remove all the characters occurring after the last '\\'. So,

new_path = \home\linux\testfile\abc

Is there a way I can do it? Slicing doesn't help because the number of characters after the last '\' isn't fixed. I know i need to post an attempt but i don't even understand how do i start this.

  • please work with os import or related Commented Jul 13, 2022 at 9:47
  • Why does slicing not work? Slice it and get the last element by using sliced_path[-1] on the resulting list. Or use rsplit Commented Jul 13, 2022 at 9:48

You can use rsplit to start from the right and only split one time.

>>> path = '\home\linux\testfile\abc\work' >>> path.rsplit('\\', 1) ['\\home\\linux\\testfile\\abc', 'work'] >>> path.rsplit('\\', 1)[0] '\\home\\linux\\testfile\\abc'

This works for me i used to think that split removes after the first occurrence.
@Pushpesh, welcome, split strat from left BUT rsplit start from right and you can also control how many split

Why not simply use pathlib? Path objects never leave trailing path delimiters.

from pathlib import Path path = Path("\home\linux\testfile\abc\work") new_path = path.parent

Does it mean that I get the parent directory

>>> a="/home/pro" >>> os.path.dirname(a) '/home'

You can try with os library.

>>> import os >>> data = os.path.split(r"\home\linux\testfile\abc\work") >>> data[1] 'work' >>> data[0] '\\home\\linux\\testfile\\abc'

You can use head, tail = os.path.split(path)

This only works if the last part of the directory is called "work"...
Yes, i know, i was giving an example, then a reference to what i used, and he can work with it. He can just os.path.split(path) then work with (head,tail) output.
Yes, but OP asked for a function that works generally, not an example...
This approach won't work for me because the last part isn't fixed.
I have edited my answer. you can just take any path into a variable and pass it to split()
