The easiest way to learn to use SnapPy is to watch the screencasts available on YouTube:
- Intro and quickstart: an 11 minute video with the basics: Part I and Part II.
- A recent hour-long demo Practical computation with hyperbolic 3-manifolds, recorded at the Thurston Memorial Conference.
- The SnapPy 2.0 new feature demo.
The key thing to remember when using the SnapPy command shell window is that you can explore objects using introspection and tab-completion:
In : Manifold? <hit return-key> ...instructions for creating a manifold...
So now we create a manifold:
In : M = Manifold("m004")
But what can we do with it?
In : M.<hit tab-key> ...list of methods...
What does the “cover” method do?
In : M.cover? <hit return-key> ...description of cover method..
