Like a matrix. Someone could submit an input whose string is just words about it. Am I unclear? Sorry. I'm still wrapping my head around all this, and my opinion (as someone who uses interacts a lot without all the advanced features) are not going to be as useful. > The example could be rewritten like this to be more consistent: > > @interact > def _(n=2, type=Integers(3)): > print n^2 > > Then Integers(3)(user input) is always run.

I just mean that it should be obvious how to avoid all the horrible things you mention earlier :) -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
