Is there some way to refer to the and * operators as functions?

Yeah, use the operator module

>>> import operator 
>>> operator.add (5, 2)
7
>>> operator.mul (5, 2)
10
>>> 

example::

If I want to have the length of a
vector v writing

reduce(lambda x,y:x+y,map(lambda x:x*x,v))

is not really nice. Instead I can write
something like:

reduce(operator.add, map(operator.mul, v, v))
