It is easy to do, even if you only have the four points describing line segments (http://www.maths.abdn.ac.uk/~igc/tch/eg1006/notes/node23.html). However, it requires that you solve for two equations. How can I do this in Python, either solve equations, or calculating intersection points some other way?

I needed this a couple years back and used parts of pycad without much 
difficulty.
