08 Python Nested if else conditional statements

In this video we will make our code more clear and easier to understand using nested if else conditional statements.
Like this we will separate our code into two functions where in first function we will make only calculations and in second function we will make only validations of user input.
This is the proper way how to write Python code, and it may be a bit confusing and many people give up on this step. So I will do my best to explain you clearly this nested if else conditional statement and in case you have any question feel free to ask me in comments below this video.
