Sourcery rule id: remove-redundant-path-exists

Section titled “Sourcery rule id: remove-redundant-path-exists”

Description

Section titled “Description”

Remove unnecessary path.exists() check.

Before

Section titled “Before”
from pathlib import Path


p = Path("/home/user/mydir")
if p.exists() and p.is_dir():
  do_sth()

After

Section titled “After”
from pathlib import Path


p = Path("/home/user/mydir")
if p.is_dir():
  do_sth()

Explanation

Section titled “Explanation”

The following functions already contain a check whether a path exists:

  • pathlib.Path.is_dir()
  • pathlib.Path.is_file()
  • pathlib.Path.is_symlink() There’s no need to explicitly call pathlib.Path.exists() before.
