How to generate random x and y coordinates using box muller transformation

I'm attempting to generate random x and y integer values within a certain range (roughly -10 to +10) using a box muller transformation.

I've logged a dataset and calculated my standard deviations for each axis as sdX = 4.413680773 and sdY = 4.361846901.

I've tried to read up about box muller transformations, however haven't been able to find much clear information that doesn't involve greek characters as I haven't done that kind of math in several years. If anybody could explain in simple english how i'd approach this, or even with python code examples that would be greatly appreciated.
