I think this should work (i.e., Integer __pow__ should be written so
that it does the pythonic thing of giving up so that python can try the
other argument's __rpow__ method). Is the fix easy?

def __rpow__(self, base):
print self

I hope this isn't old news. I just figured out how to use "lambda" as
a variable without conflicting with the Python keyword. It's very
simple -- all you need to do is put an underscore at the end of the
name:
lambda_ = var("lambda")
This is the syntax for adding a subscript, but ... no subscrip

Aha. That statement does not mean (0*d)%1 == 1. It means $ 0\times d

Maybe the examples 1.inverse_mod(0) and 0.inverse_mod(1) could be

I am trying to convert a multivariate polynomial to the symbolic ring
for manipulation. In particular, subs() for the polynomial was *really*
slow. I think the following should work.
R. = QQ[]

sreq = SR(eq)

sreq.subs(sra=3)

it looks like there are no problems now with ubuntu 9.10.
