2	Use *args for variable arguments	Makes your function flexible without manual parameter handling	def log_messages(*args):
3	Avoid if-else pyramids	Improves readability and reduces nested complexity	Use early returns instead of deep nesting
4	Use type hints	Clarifies expected input types for maintainers and tools	def greet(name: str):
5	Specify return types	Makes the function’s output clear and helps IDEs	def add(a: int, b: int) -> int:
6	Use ... in doctests to skip unimportant lines	Keeps examples concise while focusing on key parts	# doctest: +ELLIPSIS
