pybuglint

pybuglint — A modern Python CLI tool to detect and report “almost-bugs” often found in AI-generated code. Designed for developers who want clean, safe and production-ready code, with zero noise and actionable feedback.

✨ Features

• 🔍 Scan files or directories (.py).
• 📋 Built-in rules:
  • Equality vs None (== None → use is None).
  • Bare except: blocks.
  • Mutable default arguments ([], {}).
  • Shadowing Python builtins (list, dict, id, type…).
  • Residual print(...) statements (use logging instead).
• 🎨 Beautiful tabular reports powered by Rich.
• ✅ Fully tested (100% coverage).
• 🐍 Requires Python 3.12.
