An open-source book, 'The Little Book of Python Anti-Patterns', cataloging Python anti-patterns and worst practices with examples and solutions. It covers correctness, maintainability, readability, performance, security, and migration patterns for Python and frameworks like Django.

Use cases

• learn common Python mistakes to avoid
• improve code quality by studying worst practices
• find anti-patterns in Django projects
• teach Python best practices in a course
• reference anti-patterns while doing code review
• migrate legacy Python code to modern idioms

When to choose

• you want a free, example-driven reference of Python pitfalls
• you are teaching Python and want concrete bad-vs-good code examples
• you need guidance on migrating old Python or Django patterns

When to avoid

• you need a static analysis tool rather than reading material
• you need up-to-date coverage of modern Python 3.12+ idioms, as the book is no longer actively updated
• you need commercial-use rights, since content is CC BY-NC-SA licensed
