In this Python course video discussed the concept of scope in Python, which refers to the region of the code where a variable is defined and can be accessed. You can also learn about the LEGB (Local, Enclosing, Global, Built-in) rule, which specifies the order in which Python searches for a variable in different scopes.
Here are examples that demonstrated how the LEGB rule works in Python, including examples of local scope, enclosing scope, global scope, and built-in scope. Also an example of using the global keyword to modify a global variable inside a function, and an example of using the nonlocal keyword to access and modify a variable in the enclosing scope of a nested function.
