Re: [sage-devel] Making the transition from user to developer
Thanks for the great tips. And yes, I heart Python.

More concretely, for the specific project (1), have you looked into SymPy's manualintegrate module? Quoting the docs [1]: "The option manual=True can be used to use only an algorithm that tries to mimic integration by hand.

[sage-devel] Making the transition from user to developer
What would be a good way for a Sage user with a basic programming background to learn about Sage development and how codebases are built? Projects ultimately of interest so far are (1) a "show-my-steps" feature for differentiation in Sage or (2) a feature for generating proofs by induction for some class of problems. Are there any relevant tutorial-like things? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
