What are common mistakes when using default parameters in programming?
One common mistake is not considering mutable default arguments, which can lead to unexpected behavior.
Can you give an example of that?
Sure! If you use a list as a default parameter and modify it, the change will persist across function calls.
How can I avoid this issue?
You can use None
as a default value and then initialize the mutable object inside the function.
Are there any other mistakes I should be aware of?
Yes, another mistake is assuming that default parameters are only set once; they can lead to confusion if not handled properly.
