What are the best practices for parameter passing in Python?

In Python, it's best to use keyword arguments for clarity, and to avoid mutable default arguments to prevent unexpected behavior.

Can you explain why mutable default arguments are problematic?

Sure! Mutable default arguments can retain changes between function calls, leading to unintended side effects.

What are some examples of mutable and immutable types in Python?

Mutable types include lists and dictionaries, while immutable types include strings and tuples.

How can I avoid using mutable default arguments?

You can use None as a default value and then initialize the mutable object inside the function if needed.
