To improve Python code quality, apply consistent type hints, use dependency injection, and avoid unsafe anti-patterns like bare exception handlers and mutable defaults. Refactoring with these practices ensures safer, clearer, and more maintainable code.
The Result pattern in Python models expected failures explicitly without relying on exceptions. It improves robust error handling by avoiding unsafe practices like bare exception handlers, ensuring clear function signatures and reduced coupling.
Refactor Python code by adding consistent type hints to function signatures and using appropriate typing constructs. Implement dependency injection and functional patterns with simple functions to reduce coupling and unnecessary complexity.
Unsafe Python anti-patterns to avoid include bare exception handlers, mutable defaults, wildcard imports, unexplained type ignores, and global state. Avoiding these improves readability, testability, and reliability in your Python files.
Preferring simple functions over unnecessary classes improves Python type safety by reducing coupling and complexity. Combined with type hints and explicit result handling, this approach yields clearer, more testable APIs.
