Python Tutorial #4: Python Variables, overriding, dynamic typing in Python
This Python Tutorial: Python Variables video is about using of variables in Python, why do we need variables, what is overriding of variables and also this tutorial is about dynamic typing in Python.
Variables in Python are used to get rid of code redundancy. This is about compliance to DRY principle.
Variables in Python always just a reference to an object in memory. This is an essence of Python's dynamic typing, because a variable can refer to any object, no matter what is the type and value of this object.
Overriding variables in Python is just a new assignment to the variable of new value.
This video is the fifth video of my Python in depth tutorial.
