Python Complete Course #28 - Python Function LEGB rule, global keyword

👨‍💻 Source code: https://ckmobile.gumroad.com/l/aaiwpb

The LEGB rule is a kind of name lookup procedure, which determines the order in which #python looks up names. For example, if we access a name, then Python will look that name up sequentially in the local, enclosing, global, and built-in scope. It is the code block or body of any Python function or lambda expression.

In Python, global keyword allows you to modify the variable outside of the current scope. It is used to create a global variable and make changes to the variable in a local context.
