I would include a brief instruction on the Notebook page, like "Press
shift+enter to execute statements."

Indeed it would. I assumed that Ondrej was using sympify, but I guess
he isn't. It would be a good idea, though, for exactly this reason.
I would also run it through the Mathematica and Maxima parsers in
sympy/parsing, which I think will handle things like implied
multiplication and inf

Hi all,
as_coeff_exponent(...) seems to ignore derivatives, as shown below
Is this behaviour intended? If so I can report it as an issue - but
last time recorded an issue it turned out I just misunderstood atoms
(), so I thought I'd check first here! :)
Thanks,
andy

I think whatever smart parsing we implement should be implemented
right in sympify, that way we can benefit from it in regular SymPy
too. Maybe we could add a flag to sympify to only work strictly to
convert stuff to sympy expressions with python syntax like it does now
and another option

I wonder if there are any good open source mathematical expression
parsers out there that we could use their regular expressions.
