An example of an AI chatbot conversation about common scope mistakes in Python.
What are some common scope mistakes in Python?
Common scope mistakes in Python include misunderstanding local vs. global variables, and using mutable default arguments.
Can you explain the difference between local and global variables?
Sure! Local variables are defined within a function and can only be accessed there, while global variables are defined outside and can be accessed anywhere in the code.
What about mutable default arguments? Why are they problematic?
Mutable default arguments can lead to unexpected behavior because they retain changes between function calls, which can cause bugs.
How can I avoid these scope mistakes in my code?
To avoid these mistakes, always use immutable types as default arguments and be cautious about variable scope when defining functions.
