Python Annuity Calculator

[Ajax478]

Here is my first program in python. It is a annuity calculator for a future value annuity. I feel so good so now I get my annuity homework done like that with out a calc

Code: Select all



def AnnuityForm():
   
    principle=input("Please Enter Your Principle(Must Contain Cents): ")
    time=input("Please Enter How Long The Annuity Is: ")
    interest=input("Please Enter Your Interest Rate: ")
    tcompounded=input("Please Enter The Amount of Times It Is Compounded A Year: ")

    #Configuring n and i for principle forumla

    interest=interest/100.00
    interest=interest/tcompounded
    n=tcompounded*time

    #The principle formula

    part1=(1.00+interest)**n
    part2=part1-1.00
    part3=part2/interest
    total=part3*principle

    #Amount of money deposited
   
    deposited=principle*time*tcompounded

    #Total interest gained

    ttlinterest=total-deposited
   
    print ""
    print "Your final amount is $",total
    print ""
    print "The amount you deposited is $",deposited
    print ""
    print "The amount of interest you gained is $",ttlinterest
    print ""
    print ""
    AnnuityForm()


AnnuityForm()

You don't really need to put it all in a function, but it still works.

Well thats only because I wanted it to repeat because when I have to put in multiple problems one after another. If there is another way of doing that without functions please tell me thank you.

you can do it with some sort of loop.

you could set it up like this (psuedocode, i don't know python)

Code: Select all

function Enterdata()
{
// enter data here?
}

while(true)
// keep looping until killed
{
EnterData()
// possibly ask user if they want to enter data again
}


the way i believe you're doing it is a crude form of recursion, which is kinda bad practice.

Ah I see. Thanks guys. It works right now so I'll use it becuase I still need to do homework XD. But I will fix it later.
