Whether you’re building complex systems or simple scripts, these insights will help you write cleaner, more efficient Python code....
Use Type Hinting:Add type hints to your function signatures (e.g.,def get_ids() -> list:) to make expected return types explicit. Tools like [MyPy](https://mypy-lang.org/ "MyPy") can then statically check your code. Write Docstrings:Document the expected parameter types and return type...
