amt = int(str(input("Enter the loan amount in dollars: "))) n = int(input("Enter the loan duration in months: ")) r = int(input("Enter the % annual interest rate: "))/100/12 payment = str(r*amt/1 - (1+r)**(-n)) print("Your monthly payment is: " + round(payment,2)) ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The code runs but I keep getting this "TypeError: type str doesn't define __round__ method" How do I fix it?

The code should give something like this :

Enter the loan amount in dollars: 100

Enter the loan duration in months: 10

Enter the % annual interest rate: 12

Your monthly payment is: 10.56
