Python Python program help with my math code

[Juliayaho]

Hi I built this code that runs well. Is about calculating a student loan... The problem is that I wish I could create a table that will tell me in each column "payment number", "remaining balance", "interest amount", "principal amount" Can you help me do this? I am new to python and this is not for a python class... I am just trying to build a math model and I thought that since python is a free program and I have used it once before... that I could use it again during my presentation in class.

Does anyone know how I can accomplish this?
Or it doesn't even have to be a table maybe a list of all the payments broken down till is paid off...
This is my code so far.

Code:

def calcDebt (principal, interestRate, numPayments, freqPayment):
    #This code will make different predictions to pay off student loan
    #Input Meanings
    '''
    Inputs
    - interestRate  - The Interest Rate of a Loan
    - numPayments - The Number of Payments Needed
    - principal - The Original Student Loan Amount
    - freqPayment - Frequency of Payments Based on Weekly, Monthly, Annually
    - m - The Minimum Payment Rate of Student Loan
    Returns
    - paymentAmount - The Payment Amount Will Be
    - minimumPayment - The Least Amount Needed to Pay
    '''

    freqPayment_lookup = {'weekly': 52, 'monthly':12, 'annually':1}
    interestRate = float(interestRate) / 100

    x = interestRate/freqPayment_lookup[freqPayment]
    y = (1.0 + x) ** numPayments
    z = x/(y - 1.0)
    paymentAmount = (x + z) * principal

    return paymentAmount
def main():
    a = input('Student Loan Amount: ')
    i = input('Student Loan Interest Rate: ')
    n = input('Number of Payments: ')
    f = None
    while f not in ['weekly', 'monthly', 'annually']:
        if f:
            f = raw_input('Sorry! That is NOT an Option. Please Enter weekly, monthly, or annually: ').lower()
        else:
            f = raw_input('How Often Do You Want To Make Your Payments? ').lower()
            m = input('Do You Know Your Minimum Payment Rate? If So, That is: ')
    payment = calcDebt(a, i, n, f)
    print 'Your %s payment will be %.2f' % (f, payment)
    minimumPayment = a * m / 100
    minToInterest = round((i/100)/12 *a)
    minToPrincipal = round(minimumPayment - (i/100)/12 * a)
    print 'You Must Pay ATLEAST the Minimum of:', minimumPayment
    print 'IF Only Minimum is Paid, This Amount Goes to Interest:', minToInterest
    print 'IF Only Minimum is Paid, This Amount Goes to Principal:', minToPrincipal
if __name__ == '__main__':
    main()
    raw_input('Please Press Enter to Exit')

Put your code between [code] [/code] tags, then the indentation will be preserved (which is quite imprtant since this is Python).
