Question

I’m trying this example:

p = 10000
n = 12
r = 8
t = int(input("Enter the number of months the money will be compounded "))

a = p (1 + (r/n)) ** n,t

print (a)

.. but the error is:

TypeError: 'int' object is not callable

Is Python seeing p as a function? If so, is there no way I could do it without importing modules?

Thanks!

Answer 1

Assuming you are using python 3..

p = 10000
n = 12
r = 8
t = int(input("Enter the number of months the money will be compounded: "))

a = p * (1 + (r / n)) ** (n * t)

print(a)

Also double check the units for t, is it in months or years? The formula seems to suggest years (if n = 12 is months per year) but you are prompting for months.

If in python 2.x you would need to import division from __future__, or convert r to float first. And you would use raw_input for the prompt.
