Submit a python script in $.$py file

Imagine you're working on a point$-$of$-$sale system for a retail store. The store offers discounts

based on the customer's total purchase cost. The discount rules are as follows:

If the total cost is less than $$50,$ no discount is applied.

If the total cost is between $$50$ and $$100($inclusive$),$ a $10\%$ discount is applied.

If the total cost is over $$100,$ a $20\%$ discount is applied.

Write a Python program that:

Takes the total purchase cost as input.

Applies the correct discount based on the above rules.

Output the final cost after applying the discount
