Python code smells

A fast, dependency-free first pass over Python files. It does not replace a linter, it gives an agent concrete line numbers to start a review from.

When to use

  • The user asks to review, clean up or "look over" Python code.
  • Before a commit or pull request, to catch the obvious problems.
  • When a project has no linter configured yet.

How to run

python scripts/smells.py src/
python scripts/smells.py app.py utils.py --max-lines 40

Directories are searched recursively for .py files. Hidden folders and __pycache__ are skipped.

Rules

RuleMeaning
bare-exceptexcept: without an exception type hides real errors
mutable-defaulta list, dict or set used as a default argument value is shared between calls
missing-docstringa public function or class (no leading underscore) has no docstring
long-functiona function is longer than --max-lines (default 50)
too-many-argsa function takes more than --max-args parameters (default 6)
syntax-errorthe file could not be parsed

Output

JSON with files (number of files checked) and findings, a list of {"file", "line", "rule", "message"}. The exit code is 1 when there are findings and 0 otherwise.

After running

Group the findings by rule, fix the bugs first (bare-except, mutable-default), then the readability items. Do not add docstrings that only repeat the function name.

Errors

A path that does not exist exits with code 2.
