The way this works is that theInnerfunction receives a hidden parameter that tells it where theOuterprocedure’s local variables are. In practice, what is passed is a pointer to theOuterprocedure’s stack frame. Now, if the containing function or precedure happens itself to be nested, then y...
In this section, I'll explore the concept of a dictionary inside another dictionary. In Python, this is called anested dictionary. Let’s return again to your person attributes dictionary. You can make one more improvement to it. If you're following along in a Jupyter notebook, can you ...
Yes, ‘break’ can be used in nested loops. When encountered, it breaks out of the innermost loop where the ‘break’ statement is placed. In which loop control structures can 'continue' be used? Can 'break' or 'continue' be used outside a loop? How does 'break' affect nested loops...

In a programming language, the word scope is sometimes used to define the realm in which an object, such as a movie clip, lives. A movie clip might exist in one part of a Flash movie but not another. For example, a child movie clip might be nested inside one of two movie clips fou...
Scopes nested inside class definition ignore names bound at the class level. A generator expression has its own scope. Starting from Python 3.X, list comprehensions also have their own scope.▶ Rounding like a banker *Let's implement a naive function to get the middle element of a list:...
