chi-squared tests in python?

[Matthew Vernon]

Hi,

I'd like to be able to use the chi-squared test in my code. Currently,
I can output "look up [this value] in a chi-squared table with [x]
degrees of freedom", but that's obviously a little sub-optimal. I
notice that numarray has a chi_square function, but that just gives
you random numbers from a chi-squared distribution with a set number
of degrees of freedom - not really what I want.

Does there exist python code to do this? preferably something vaguely
standard? 

Thanks,

Matthew
ps: given the "batteries included" philosphy, there's a remarkable dearth 
of stats in python...
