Yes, you can use the builtin function reduce for this ...

... immediately:

 >>> from operator import add
 >>> reduce(add,[1,2,3,4,5,6])
21

reduce is even more versatile than this "Capital sigma" (- which, 
incidentally,
 on my email-client appears like the å in Lyckå), for instance:

 >>> from operator import mul
 >>> reduce(mul,[1,2,3,4,5,6])
720

Was this fast e3nough?
