What is variable scope in Python?

Can you explain what variable scope means in Python?

Sure! Variable scope refers to the visibility and lifetime of a variable in a program. In Python, there are mainly two types of scopes: local and global.

What’s the difference between local and global scope?

Local scope means the variable is accessible only within the function it is defined in, while global scope means the variable can be accessed anywhere in the code.

Can you give me an example of local and global variables?

Of course! For example, if you define a variable inside a function, it's local. If you define it outside any function, it's global.

What happens if I try to access a local variable outside its function?

You will get a NameError because the variable is not defined in that scope.
