## Problem Set 1 ## Gather user input outstandingBalance = float(raw_input("Please enter the outstanding balance on your credit card: ")) interestRate = float(raw_input("Please enter the interest rate on your credit card as a decimal: ")) minPayment = float(raw_input("Please enter the minimum monthly payment on your credit card as a decimal: ")) ##Initialize variables currentMinPayment = 0.0 principlePaid = 0.0 interestPaid = 0.0 month = 1 remainingBalance = 0.0 ##Run loop while month<=12: print(type(currentMinPayment)) print(type(minPayment)) print(type(outstandingBalance)) currentMinPayment = round(minPayment * outstandingBalance,2) interestPaid = round (interestPaid + ((interestRate/12)*outstandingBalance),2) principlePaid = round(principlePaid + (currentMinPayment  interestPaid), 2) outstandingBalance = round((outstandingBalance  principlePaid), 2) ##Make all into strings currentMinPayment = str(currentMinPayment) interestPaid = str(interestPaid) principlePaid = str(principlePaid) outstandingBalance = str(outstandingBalance) month = str(month) ##Print all out print ("Month: " + month) print ("Minimum monthly payment: $" + currentMinPayment) print ("Principle paid: $" + principlePaid) print ("Remaining balance: $" + outstandingBalance) ##Change month to int and increment month month = int(month) month = (month +1) ##Change then back to floats currentMinPayment = float(currentMinPayment) interestPaid = float(interestPaid) principlePaid = float(principlePaid) outstandingBalance = float(outstandingBalance) month = int(month)

I don't like converting variables to strings and back to numbers. Unless the course requires it, I say don't do it. You can have str( aFloatOrInt ) in a print statement/function. I've also at times had variables like numberString, which is the string of my number for printing.

I was having trouble with print statements with the variables as strings, i.e. print "Month: " + month, when month is an int, was resulting in an error, thus the conversions

Not sure if it's in the conversion or the casting back, but you have a multiplier being added to your values.

Put in 2500 as a minimum payment and it prints Minimum monthly payment: $250000.0

Oh, because you are multiplying it by the outstanding balance: currentMinPayment = round(minPayment * outstandingBalance,2) I would say that you need to hammer out your logic before you worry too much about formatting on your printout. Once you have it working mathematically, then format your output.

use a comma instead of a plus sign in the print statements. what is weird about the results

How about the fact that you input a monthly payment of $0.05 and it makes it $50.00? You would never be able to pay off $400ish in 12 months, at 10%, with only a nickel paid each month.

@eSpex .... the prompt is a bit misleading  that is supposed to be asking for a monthly payment Rate.
