modern-python-patterns

Adopt modern Python patterns by enforcing PEP 585/604 type hints across function signatures, replacing untyped dictionaries with dataclasses, and migrating conditional logic to pattern matching for improved readability and type safety.

Replace os.path with pathlib by adopting object-oriented file path objects for cross-platform safety, managing resources safely through modern context managers and idiomatic file interactions during code refactoring.

You need Python 3.10+ pattern matching when replacing complex conditional logic with readable match/case constructs, improving code maintainability and clarity across data processing, web services, and CLI projects.

Yes, you can enforce modern Python idioms during code reviews by validating consistent application of PEP 585/604 typing, dataclasses, pathlib, f-strings, and context management best practices across new and refactored code.

Yes, this approach works for both new and refactored Python 3.10+ projects. Applying modern idioms like dataclasses, typing, and pattern matching improves readability, maintainability, and type safety across data processing, web services, and CLIs.
