os-path-isabs (PTH117)#

Derived from the flake8-use-pathlib linter.

What it does#

Checks for uses of os.path.isabs.

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_absolute() can improve readability over the os module's counterparts (e.g., as os.path.isabs()).

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


import os

if os.path.isabs(file_name):
    print("Absolute path!")

Use instead:

from pathlib import Path

if Path(file_name).is_absolute():
    print("Absolute path!")
