os-path-isfile (PTH113)#

Derived from the flake8-use-pathlib linter.

What it does#

Checks for uses of os.path.isfile.

Why is this bad?#

pathlib offers a high-level API for path manipulation, as compared to the lower-level API offered by os. When possible, using Path object methods such as Path.is_file() can improve readability over the os module's counterparts (e.g., os.path.isfile()).

Note that os functions may be preferable if performance is a concern, e.g., in hot loops.


import os


Use instead:

from pathlib import Path
