Python electric potential loop

For this assignment, we were asked to construct a 3D model of 3 point charges along with their observation points in Vpython. We were given two options of how to construct our 3D model, I chose the loop method. 

First, k constant and pi were defined. Then, using the coding we used in class I was able to re-write that code and construct my model. I created new locations and new charges, then wrote in the formulas in order to find their electric potential with respect to their corresponding observation points. My final result is pictured below along with its coding.
