In addition to the other solutions there is the (more generic?) use of the
operator module and reduce function:
import operator
reduce(operator.add, (1,2,3))
Explore operator to see what other functions you can use.
Also there are the array handling modules such as numarray.
You can also define your own classes based on list and write methods to do
these operations.
