What are some common mistakes with default parameters in programming?

Common mistakes include using mutable default arguments, which can lead to unexpected behavior, and not considering the order of parameters.

Can you explain why mutable default arguments are problematic?

Sure! If you use a mutable object like a list as a default parameter, it retains changes across function calls, which can lead to bugs.

How can I avoid these mistakes?

To avoid these mistakes, use immutable types as defaults or set the default to None and handle it inside the function.

Are there any best practices for using default parameters?

Yes, always document your parameters, use clear naming conventions, and consider the implications of your defaults on function behavior.
