Uise thespecificed name for your sceripes (shown in purentheses bekow).Mortgage Calculator(mortgage.py) Write a mortgage cakulator that includes compound innetest. The total mongagecalculation requires three inputs: principal (in dollare), interest rate, and time (in years). Your programshould have three functions: total_mortgage, display_title, and main.total_mortgage should take the three values as parameters: principal, annual interest rate, and years,and it should caleulate and display the total mortgage amount, formatted with comma separators, to twodecimal places.Here's the formula yonu should use in total_mortgage:where a is the total amount due, pis the principal, r is the annual interest rate (fixed), and t is the timeperiod in years. This would be the amount you would have to pay if you borrowed the principal ar theannual interest rate for the specified period of years (not amortized).Your display title function sbould simply display "Mortgage Calculatoe", as shoen in the examplebelow.Your main function should first call the display title function, then prompe for three values,using three separate while koops to ensure valid input. Principal should be a positive float, interest rateshould be a float greater than I and less than 10, and years should be a positive integer berween 5 and 30(inclusive). The main function should then call total_mortgage and pass the three valuesExample:Mortgage CalculatorPrincipal S: -5Principal S: 300000Interest rate t: 3.375Term (years): 7000Term (years): 30Amount: $812,057.78

The following approach is to be followed: Define a mortgage calculating function and calculate the…
