How to check the presence of a given file in a given directory using os.listdir()?

Question

Python

Hello, there is a main.py file in the Project folder. In this folder besides main.py there are various other files (.txt, .jpg, .mp3 etc ), how can I check if a given file is in this folder/directory using sys.argv[0] and os.listdir () . That is, if my file (main.py) is present in this folder, then display "yes", otherwise "no" (check with an if-else loop)
Thanks in advance....

Something like this. The resolve() method is needed to deal with elements like .. and symbolic links, and get absolute paths.

from pathlib import Path
target_path = ... #определяешь целевой путь

if Path(sys.argv[0]).parent.resolve() == Path(target_path).resolve():
    print('Тот же путь!') #оба пути указывают на один каталог
