Calculating Pi Using Taylor Series

I am trying to calculate the value for Pi using Taylor Series. Below is the code that I have, but when I run the program I get a list of 1's and 0's.

Here is my code:

from math import *
import numpy as np

n= 100
x= 1
series = []

for i in range(0,n):
    value = (x**(2*i+1)*(-1)**i)/(2*i+1)
    series.append(value)

print series

I believe you're running into the same issue as this one, which is trying to divide one list by another list. Take a look at the suggestions there and I think you'll find your answer.

The error message is telling you all you need to know. You are trying to divide two lists even though you might not think it looks like it. [] in Python indicate a list, even though they can be used as brackets in real math. All you have to do is change 

value = [x**(2*i+1)*(-1)**i]/[2*i+1]

to

value = (x**(2*i+1)*(-1)**i)/(2*i+1)
