What are mutable default parameters in Python?
Mutable default parameters are default argument values that can be changed, like lists or dictionaries.
Can you give me an example of how they work?
Sure! If you use a list as a default parameter, modifying it in one function call affects future calls.
That sounds risky. How can I avoid issues with mutable defaults?
A common practice is to use None
as a default and then initialize the mutable object inside the function.
