glob (PTH207)#

Derived from the flake8-use-pathlib linter.

What it does#

Checks for the use of glob and iglob.

Why is this bad?#

pathlib offers a high-level API for path manipulation, as compared to the lower-level API offered by os and glob.

When possible, using Path object methods such as Path.glob() can improve readability over their low-level counterparts (e.g., glob.glob()).

Note that glob.glob and Path.glob are not exact equivalents:

glob Path.glob
Hidden files Excludes hidden files by default. From Python 3.11 onwards, the include_hidden keyword can used to include hidden directories. Includes hidden files by default.
Iterator iglob returns an iterator. Under the hood, glob simply converts the iterator to a list. Path.glob returns an iterator.
Working directory glob takes a root_dir keyword to set the current working directory. Path.rglob can be used to return the relative path.
Globstar (**) glob requires the recursive flag to be set to True for the ** pattern to match any files and zero or more directories, subdirectories, and symbolic links. The ** pattern in Path.glob means "this directory and all subdirectories, recursively". In other words, it enables recursive globbing.

Example#

import glob
import os

glob.glob(os.path.join(path, "requirements*.txt"))

Use instead:

from pathlib import Path

Path(path).glob("requirements*.txt")
