I for one think we should keep sympify() (and the S() shortcut). sympify()
gives a nice character to SymPy, as a function named after it. I certainly
don't see why you would want to delete sympify() and just keep S(). How is
that better than just keeping sympify() but always using S()? And b

Contracting "convert" to "cv" is *not* easy to underst
Hello,
I think that S is usefull but "mystic" for new user.
Instead of sympify, you could propose the name cvToSympy alias "convert to
sympy". It's longer but easier to understand.
Best regards.

I believe you just have (-1)**r = exp(r*I*pi). Are you thinking of the
3 possibilities for x**3 + 1 = 0?

Yes, that would be...but it's SYMpify not SIMpify. But yes, they are
close. I (as has been pointed out) almost exclusively use S() and so
it's not a problem. Would there be any reason not to delete sympify
from the namespace and just
I'm away from my own computer right now, Vinzent, but from what you've
shown above this looks like an issue in distributing the minus sign
(what I refer to as the 2-arg mul: a constant distributes over a
single Add). There is another matrix test, I believe, that had that
problem and it was handled
This is a known problem. See
http://code.google.com/p/sympy/issues/detail?id=1916. There is a workaround
there that you might try.
Unfortunately, not many of us use Windows, so fixing this issue has taken
longer than it might (the issue only exists on Windows).

There's also the S() function, which is basically a shortcut to sympify().

i think this works only on linux because the first time i put Plot(x,y) the
error is
Window initialization failed: Unable to share contexts
then again i use the above command then second error is
Window initialization failed: exception: access violation reading
0x
This issue makes me to think about renaming the simpify function to
something more different from simplify. Possible candidates could be
parse_expression, str2sympy, str2expr etc.
The similarity between "simpify" and "simplify" is misleading.

THE ABOVE THING IS NOT WORKING IS SHOWING THE SAME ERROR
