Can you explain if default arguments in Python can be mutable?
Yes, in Python, default arguments can be mutable. However, this can lead to unexpected behavior.
What do you mean by unexpected behavior?
If a mutable default argument is modified, it retains the changes in subsequent calls, which can cause bugs.
Can you give me an example of this?
Sure! If you use a list as a default argument and modify it, the changes will persist across function calls.
