Question 1: What are mnemonic variable names? Why is a good practice to use them?

Ans 1: mnemonic variable names is basically the name given to any variable by us which helps us remember what is there in that variable. For example, just assume that I want to store the price of onion in a variable then I would proabably name the variable "Onion_price" because just assume that I am looking at this variable after a long time it will click in my mind right away that "ok, this simply contains the price of onion". So yeah it is a very convenient practice to acquire.

Use variables and suitable data types in python to solve the following. Add comments to explain why you did what you did. Use mnemonic variable names.
