OK, this is the idea that I came up with. It is also necessary to strip out the "..." that come at the start of indented lines, the <html> lines corresponding to the pretty-printed output, etc. I guess I just assumed that this must already have been done and be easily accessible, since it seems like a reasonably obvious thing to want to do -- use the nice notebook interface to create a document, and then convert it to plain Python and/or Sage to use for whatever. > > (2) You could tinker around with Notebook, Worksheet, and Cell objects > in Sage (using a script, command-line, or notebook interface).
