What I think very confusing is that 1/4 is the Sage division and not the Python standard one, so why it would be different for randint ?
I'm a teacher and the problem is not from my point of view but it will be a tricky thing to explain to my students which are in "french lycée" (sorry, I don't know the english equivalent level). There are only 18 years old and the programmation is only a tool... Christophe 2012/9/19 D. S. McNeil <dsm...@gmail.com> > > I really think that this is illogical.
