Context Managers
The with statement guarantees setup and cleanup (files, locks, connections), even when errors occur.
Type Hints
Optional annotations describing expected types — checked by tools like mypy and Pyright, ignored at runtime.
Generics
Type variables let functions and classes work over any type while staying type-safe.
Structural Pattern Matching
match/case (3.10+) matches values by shape — literals, sequences, mappings and class patterns.
Regular Expressions
The re module finds and extracts text patterns.
Functional Programming in Python
First-class functions, map/filter, comprehensions, functools and immutability.
