10-13. Verify User: The final listing for remember_me.py assumes either that the user has already entered their username or that the program is running for the first time. We should modify it in case the current user is not the person who last used the program.
Before printing a welcome back message in greet_user(), ask the user if this is the correct username. If it’s not, call get_new_username() to get the correct username.

All information needed for this will be passed to the program on the command line. There will be no user input during the execution of the program. You will need a few pieces of information. The price of the home and the amount of the down payment. You will also need to know the interest rate and the term of the mortgage. To figure your mortgage payment, start by converting your annual interest rate to a monthly interest rate by dividing by 12. Next, add 1 to the monthly rate. Third, multiply the number of years in the term of the mortgage by 12 to calculate the number of monthly payments you’ll make. Fourth, raise the result of 1 plus the monthly rate to the negative power of the number of monthly payments you’ll make. Fifth, subtract that result from 1. Sixth, divide the monthly rate by the result. Last, multiply the result by the amount you want to borrow.…arrow_forward
