What are the best practices for using default parameters in Python?
Using default parameters can simplify function calls. It's best to use immutable types like strings or tuples as defaults.
Why should I avoid using mutable types as default parameters?
Mutable types like lists or dictionaries can lead to unexpected behavior since they retain changes across function calls.
Can you give an example of a function with a default parameter?
Sure! Here's a simple example: def greet(name='Guest'):
. If no name is provided, it defaults to 'Guest'.
What happens if I change the default parameter inside the function?
If you change it, it will only affect that specific call. The default value remains unchanged for future calls.
