What are some common errors in Python parameter passing?

What are some common errors in Python parameter passing?

Common errors include mutable default arguments, incorrect argument order, and misunderstanding of *args and **kwargs.

Can you explain mutable default arguments?

Sure! Using a mutable object like a list as a default argument can lead to unexpected behavior because it retains changes across function calls.

How can I avoid issues with mutable default arguments?

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

What about *args and **kwargs?

*args allows you to pass a variable number of positional arguments, while **kwargs lets you pass keyword arguments as a dictionary.
