Python tutorial #7: Python Namespaces and Scope
This Python Namespaces and Scope tutorial is about what is namespace in Python, what is scope in Python, and why they are needed.
What is the difference between Python namespaces and scopes.
Python Namespace is a dictionary that contains names (function names, variables names, class names etc.) and their values. The value of such Python name is an address in memory where the certain object is located.
Python Scope is a path of search - where Python looks for a name's definition.

Timecodes:
00:00 - Beginning
00:28 - Python local variables. In Python parameters of a function are the local variables of the function.
02:37 - Encountering Python namespace. Python functions create a new namespace to store local variables in it.
05:17 - What is Python namespace?
08:06 - How does Python figure out in which namespace it should write a specific name, and its value? The place where an assignment is performed determines the namespace where the name will be located.
08:40 - What is a Python scope? LEGB - local, enclosed, global, built-ins.
14:21 - The Python's scope determines in which namespace Python will look for a particular name, and in what order Python will look for it.
