As stated by another comment, I would do something like :

def multiply(object, factor):
   try:
     return [ multiply(i,factor) for i in object ]
   except TypeError:
     return object*factor

This function will, recursively multiply a nested list of numbers by 
"factor" ...

I think you are referring to the Numeric or the numarray modules. They 
offer matric computations close to chat Matlab offers. "numarray" is the 
newer version of "Numeric", but in case of small matrix, it performs 
slower (for various reasons). Then, you can find lots of information on 
the net concerning these two modules.
