Question

Homework 1 Part 2 Question:
With the code down below I am trying to calculate how many months I need pay off the credit balance. The trouble I have is when I enter the input it output nothing.
#Problem 2
balance = float(raw_input("Enter the outstanding balance on your credit card:"))
year_int_rate = float(raw_input("Enter the annual credit card interest rate as a decimal:"))

#Calculations
monthpay = 10.0
month_int_rate = year_int_rate/12.0
month = 0
while balance > 0.0:
month = month+1
balance = balance*(1+month_int_rate)-monthpay

Answer 1

In that code, there isn't any statement to output anything, so the computer doesn't output anything. Computers don't do what you want, they do EXACTLY what they're told to do. Right, wrong or indifferent.

Answer 2

Just like rsmith6559 said, there is no output in the code, my middle school computer tech teacher always said; "Computers are stupid and sarcastic, they only do exactly what their supposed to do." Hopefully me and rsmith6559 helped you out.

Answer 3

I forgot to attach the print statements that I had. Apparently there was a limit to how much text I used.

Answer 4

Here is the rest of the code.
#print results
print "RESULT"
print "Monthly payment to pay off debt in 1 year:", int(monthpay)
print "Number of months needed:", month
print "Balance:", round(balance, 2)

Answer 5

I copied and pasted your code into a file on my machine. When I ran it, it ran fine. It printed out the results without change. Since you're having issues with the output, it begs the question, are you running it in Python2 or Python3 where print has changed from a statement to a function?

Answer 6

I don't have Python 3 but Python 2.7. Although not having versions 2.5 or 2.6 may have resulted in not having an output.

Answer 7

As long as you have Python2, you're fine. The differences between 2.5x, 2.6x and 2.7x are very minor. TBH, I've only run across them a couple of times, and I've been using Python since 1.51.

Now it's getting interesting. Could you copy and paste the shell where you're running your program, please? Is the program hanging up, or is it returning without outputting anything? Could you post your code on PasteBin.com? Indentation is important in Python, and we need to see the code as written, not spread over two posts.

Answer 8

Thanks for your help. I figured out what was wrong and it was my code.
