Okay, I used hasattr instead. I should really stop using quick expedients :)
All the tests passed.

I just ported your code to GiNaC - C++ - just to see how it fares in
comparison. Here are the results
Can this be passed in now? I didn't see any more comments on the
issues page.

You could try doing this :
x,k=symbols('xk')
f= lambda n : Integral(x**k*exp(-x),(x,0,oo)).subs(k,n)
f(2)
Integral(x**2*exp(-x), (x, 0, oo))
f(2).doit()
2
This works only for integers, for real n, try making use of quad in
scipy - and libmpf (?).

How come there are two data descriptors:
x.is_Real and x.is_real
for the same thing ??

Turns out, aima-python isn't exactly ideal for use in sympy yet. So
it'll need quite a lot of tweaking :)

I'll probably keep a port of Fabian's assumptions system, until the
logic module is accepted. :)

Hello,
I'm planning to apply for Summer of Code this year, to work on
the logic and sets. I have the following plan for the summer -
Boolean Algebra
/\
/ \
| Set Algebra
| |_ Cardinal Numbers
| |_ Relations
| |_ Venn Diagrams, probably use pyglet
| |_ Graph Theory
| |_
offset any slowdown because of using the layer.
This will make the things in sympy.core much easier to debug.
Am speaking gibberish?

Well, but still it's fishy. Could you please execute that test by
hand? E.g. undo the patch and do:

As a sidenote, should this fail ?
((-x)**2)**Rational(1,3) == ((-x)**Rational(1,3))**2
Documentation for x says its assumed to be real. But neither ,
x.is_real
x.is_Real
False
returns True.

Note: boolalg/test.py is not a test! Its an example of usage
to bring it
back from obsoletion, than write something from scratch - I haven't
really had a look at the old Sets module.

If you're using Fedora 10, I guess doing
yum install python-sympy
should do the trick.

Hi Ondrej,
I think I've fixed it. As you said, it was something in the printing/
str.py.
In doing that I came across this,
(x/sin(x)).args()
(x,sin(x))
(cos(x)/sin(x)).args()
(1/sin(x),cos(x))
Shouldn't
(cos(x)/sin(x)).args()
give
(cos(x),1/sin(x))
??
