I am having concerns with the validity of the code I wrote for the exercise from the book Python Programming: An Introduction to Computer Science (2nd Edition) by John Zelle.
It says:
Write a program that approximates the value of π by summing the terms
of this series: 4/1 - 4/3 + 4/5 - 4/7 + 4/9 - 4/11 + ... The program
should prompt the user for n, the number of terms to sum, and then
output the sum of the first n terms of this series. Have your program
subtract the approximation from the value of math.pi to see how
accurate it is.
Here is what I have done:
I'm using Python 3.6.
