Thanks,
Can you indicate to me the class or give me some other hints.

Does anyone know how to fix this problem in Py3.2:
...

TypeError: unhashable type: 'RegularPolygon'
What makes something hashable or unhashable? Everything passes in 2.7.

Help on function diff in module sympy.core.function:

Differentiate f with respect to symbols.
This is just a wrapper to unify .diff() and the Derivative class; its
interface is similar to that of integrate(). You can use the same
shortcuts for multiple

I'm using the 0.7.1 version for win32. Come to think of it, I -am-
using 64 bit windows, rather than 32 bit, could that be a factor?
I don't see where the development versions are. Out of curiosity,
those who are running this successfully, what versions are you using?

I wonder if anything with Shur polynomials would be of interest:

I'm writing a library that depends on sympy and I was having trouble

No rush. You've done the smart thing and started talking to us quite
early, so you can afford to take your time and get things right.

We don't have anything like that supported directly. If you want to
see how the code path works, the easiest way would be to step through
it with a debugger, like pudb.

Hi Aaron.
Thanks for the quick reply. I think I understand the printing behavior a
lot better now, and why it's that way.
The one thing I would suggest is adding a list of the printing methods to
the docs there. As far as I can tell, the printmethod values are only in
the source. Maybe under the
29 matches
