What are the scope rules in Python?
An example of an AI chatbot conversation about Python's variable scope rules.
What are the scope rules in Python?
In Python, scope refers to the visibility of variables. There are four main scopes: local, enclosing, global, and built-in.
Can you explain local and global scope?
Local scope refers to variables defined within a function, while global scope refers to variables defined outside any function.
What happens if I try to access a local variable outside its function?
If you try to access a local variable outside its function, you'll get a NameError because it's not defined in that scope.
Are there any best practices for using global variables?
Yes, it's generally best to minimize the use of global variables to avoid unexpected behavior and maintain code clarity.
