How to display a variable without a specific part?

Question

So, i have a variable, for example dir = "Crypter.aes". I need to variable like dir, but without .aes. What gotta I do for that? I use directory parser, that make many dir with file name in that directory, and for each file I need to remove a certain part at the end - .aes

Beside the point, but don't use `dir` as a variable name since it shadows the [builtin `dir`](https://docs.python.org/3/library/functions.html#dir). — wjandrea, Jul 22 '20 at 16:26

It doesn't work with my script. I make script with pyAesCrypt, that has syntax like ```pyAesCrypt.decryptFile(inputFile, outputFile, password, buffersize)```. Input file is file with ```.aes``` in the end, output file gotta be with out ```.aes```, but when I use this method, I get error " File "..." was not found" — ツHayKor, Jul 22 '20 at 16:36

This is a task for the os.path module in the standard library.

import os.path

dir, _ = os.path.splitext("Crypter.aes")

If you're working a lot with file paths, you also might want to take a look at the pathlib module.

from pathlib import Path

dir = Path("Crypter.aes").stem
