What it does #

Checks for uses of the open builtin.

Why is this bad? #

pathlib offers a high-level API for path manipulation. When possible, using Path object methods such as Path.open() can improve readability over the open builtin.

Examples #

with open("f1.py", "wb") as fp:
Use instead:
from pathlib import Path
with Path("f1.py").open("wb") as fp:
