Question

Problem set 1(a):
I coded it right but somehow my code is only showing integers in this form 16.0,no digits after the decimal.
can anyone help?

Answer 1

here is my code:

balance=float(raw_input("ENTER BALANCE"))
annual_r=float(raw_input("ENTER ANNUAL RATE"))
monthly_r=float(raw_input("ENTER MINIMUM MONTHLY PAYMENT RATE"))
month=1
min_mon_pay=0.0
i_paid=0.0
p_paid=0.0
remaining_balance=balance
total_paid=0.0
while month<=12:
min_mon_pay=float(monthly_r*balance)
i_paid=float(annual_r*balance/12.0)
p_paid=float(min_mon_pay-i_paid)
remaining_balance=float(remaining_balance-p_paid)
print "Month:",month
print "MINIMUM MONTHLY PAYMENT:"+str(round(min_mon_pay,2))
print "Principle Paid:"+str(round(p_paid,2))
print "Remaining Balance:"+str(round(remaining_balance,2))
total_paid+=min_mon_pay
month+=1
print "RESULT : "
print "Total Amount Paid",round(total_paid,2)
print "Remaining Balance",round(remaining_balance,2)

Answer 2

The problem with your code is that you need to update the balance inside the loop, so you wont keep getting always the same min_mon_pay, something like balance = remaining_balance. Also inside the loop, there's no need to do float conversion since you already did it when reading the values at the beginning. Hope it helps.

Answer 3

@halr2s I'm updating the bal inside the loop only.

remaining_balance=float(remaining_balance-p_paid)

this is inside my loop,are you talking about something else?

Answer 4

Sorry I wasn't clear enough, notice how the line...
min_mon_pay=float(monthly_r*balance)
is using a constant balance, you need to change that so that it reflects the updated balance, otherwise you'll keep getting the same min_mon_pay every time through the loop.
