This is the Python implemention of Sigma. This computes two values, the sum, sum , and the number of elements, n .
What does sigma mean in Python?
A sigma (∑) is a Summation operator. It evaluates a certain expression many times, with slightly different variables, and returns the sum of all those expressions. For example, in the Ballistic coefficient formula. The Python implementation would look something like this: # Just guessing some values.

A series can be represented in a compact form, called summation or sigma notation. The Greek capital letter, ∑ , is used to represent the sum. The series 4+8+12+16+20+24 can be expressed as 6∑n=14n . The expression is read as the sum of 4n as n goes from 1 to 6 .
