Dear All,
Just a quick note to say that pypi is slightly out of date. Also, I
use easy_install to install python packages, and although easy_install
works with sympy, there are a lot of warning messages.
The warning messages are mainly about not having __init__.py files in
your directories.

That's because S is imported in the sympy module:
In [1]: S
Out[1]: S
In [2]:
I've just found out that it's not 'E' that's causing the problem, it's
'S'.
sympify('S') #works
sympify('S*X') #doesn't work

Hi Colin,
The problem with 'S' is that it is a singleton factory:
In [8]: sympify('S.Zero')
Out[8]: 0
In [9]: sympify('S.One')
Out[9]: 1
So sympify('S*x') can't work:
In [10]: sympify('S')
Out[10]: S
In [11]: type(_)
Out[11]:
For the similar reason sympify('lambda') does not work:
In [13]
Hi Ondrej,

Could it be because in setup.py you have:

I'm new to this list and was interested in sympy to use it to help

I had a question: I would like to have a symbol, say "_" --without the

Thanks Friedrich for ans
Yeah, I tried to use from math import * (to avoid look ups), but I
failed somehow.
Anyway, here the result of Sage's timeit for evaluating f(1.0r)

dear ondrej,
thanks for the quick reply!
well, it is in the good direction. Indeed I would need to get rid of
the funcion call parenthesis, even if that is not pythonic. I actually
thought that _ could be a singleton object which, when its __add__,
__mul__, ... are called, returns a subclass of

well, it can be made "static" with this:
import __builtin__
__builtin__._ = WhatEverYouWant()

The same you can achieve with:
In [25]: f = a*x + b*c*x*z*w**2*exp(-y)
In [26]: h = f.subs({x: x(t), y: y(t)})
In [27]: h.diff(t)
Out[27]:
d 2 -y(t) d 2 -y(t) d

Oh, this is rea
How would you do this is x and y are passed as a list and you did not
know their names, ie x and y
but rather say they would be vlst[0] and vlst[1] ?

Do you mean something like that?

Hi all,
Since the deadline of GSoC2008 has been extended one more week, I
think I may refine my applications better.
I have submitted two applications and I hope you guys could give
me some comments on how to improve them. Thanks!
