Question

I'm working ps2 of p1 in the 2012 course.
I want to know how to solve this problem without defining variables in python.
I tried 20 mor times. I'm getting error.
Anyway,Thanks ..

This is my code...
month = 0
totalPayment = 0.0
"""balance =float(raw_input("balance \n"))
annualInterestRate =float(raw_input("annualInterestRate \n"))
monthlyPaymentRate =float(raw_input("monthlyPaymentRate \n"))"""
while month < 12 :
if (balance != 0)and (balance > 0):
month = month + 1
monthlyInterestRate = annualInterestRate / 12
monthlyPayment = monthlyPaymentRate * balance
print " \n\n\n The minimum monthly payment for month",month,"is " ,round(monthlyPayment,2)

totalPayment = totalPayment + monthlyPayment
print " \n The total amount paid for month",month,"is ", round(totalPayment,2)

balance = (balance - monthlyPayment)*(1 + monthlyInterestRate)
print " \n the remaining balance for month",month,"is ",round(balance,2)

else:

print " \n monthly payment and the remaining balance ",str(balance)," " ,str(totalPayment)
break
print " \n \n total payment "
print round(totalPayment,2)
print " remaining balance"
print round(balance,2)

The output from the grader..
We couldn't run your solution.

Please help me..

Answer 1

u dont need to define them at all.....no raw inout no nothing...since their grader does that automatically.....just write it as if they were defined.

Answer 2

plus ur code is extrimely long and complicated or better said "dressed" go for a more clean and simple way. gl

Answer 3

I agree with @MicroBot clean out those raw inputs an try to cut out the fat from this code; it's darn hard to read!

Answer 4

Actually your code seems fine if you cut out the raw inputs.
Just don't forget to assign a value for monthly payment rate and you should be fine.

Answer 5

There may be a chance that the grader wants you to print things out with the prompts it gives you. It may not like the fact that you altered the print statements. That's just a guess though.

Answer 6

What @TuringTest says about the print statement for the grader, is true .It wants u to have the exsact output.

Answer 7

Dont you need something also to calculate the total paid?
