I understand this works:
C = sage.server.notebook.cell.Cell(0, '2+3', '5', None)
C.id()
But I don't know understand how you can find that out for some arbitrary cell.
So far, the only way I know how is to use the interact decorator, and see what cell ids are used in the HTML.
User code can access the cell id using sagenb.notebook.interact.SAGE_CELL_ID. This is an unsupported variable, though, and may change in the future. It works for right now, though.
Unsupported in the sense that there is no guarantee it will be around in the future. It works in the Flask notebook. It does not work in the cell server (but I can tell you the "cell" id: it's going to be 1 :). And no, I think that's pretty much the only clean way to access the cell id.
There must be a way to access this from Python. Meanwhile, if you click the "Edit" button, you'll see output like this:
{{{id=3|
Sq(4)**2
///
Sq(2,2)
}}}
I believe that id=3 means that the cell's id is 3. (The input is Sq(4)**2, and the output is Sq(2,2).)
Thanks. Don't know how I missed that. I guess I'll just make a new worksheet, and not delete cells so they're nice and orderly.
