Day 13: Pay Your Tax
Write a function called your_vat. The function takes no parameter. The function asks 
the user to input the price of an item and VAT (vat should be a percentage). The 
function should return the price of the item plus VAT. If the price is 220 and, VAT 
is 15% your code should return a vat inclusive price of 253. Make sure that your 
code can handle ValueError. Ensure the code runs until valid numbers are entered. 
(hint: Your code should include a while loop).
