print "all amounts should be in dollars!"

while True:
	P=float(raw_input("enter Principal:"))
	i=float(raw_input("enter Percentage of interest rate:"))
	t=float(raw_input("enter Time(in years):"))
	I=P*t*(i/100)
	print "Interest is", I,"dollars"

Discussion

there're some problems with the script,such as not being able to input divided amounts such as "8/12" which is specially needed in the "time in years" field,any advice?

    I think line7 show be changed to: I=P * (1 + i/100.0) ** t

    you could set the t=int(raw_input("enter time(in months) :"))

    set Interest=principal(t/12)interest

    the (t/12) converts the time back to years, and since I is fload, it can easily accomodate the result
