```Hi,

sorry I don't know the conventions yet.

I'd need to know how to create a line between two points. I don't know
after many hours checking, how to convert this pseudocode to python.

line = new Line( pointList[startPoint], pointList[endPoint])

I've done point list and indexes already, put don't know how to create the
line.

Laura
