I'm a novice programmer. I have a decent understanding of algorithms but I don't have a lot of computer science/software engineering experience. As a way to help me learn, I've begun a coordinate geometry program similar to the COGO program developed years ago at MIT. Currently, I store the points in a dictionary in the format point_number : [North, East]. I eventually will add a Z component to the points and possibly a description after I get enough of the horizontal geometry worked through. I would like to be able to save the point table so that I can have multiple projects. My main python script is below. It reads in a text file that contains commands to create/calculate the location of the various points. My question is what is a good method to store the point data outside of python? I eventually will also add the capability to define a baseline that consists of multiple points with some attributes to define relative locations along the baseline (stationing).
I use enthought canopy express with python 2.7.11 on windows 10 64 bit.
