How to separate the values in an element to add them

[deanhystad]

Lots of ways to do this. Here are a 3 more.

from functools import reduce

values = '1,2,3,4,5'

print(sum(int(n) for n in values.split(',')))
print(sum(map(int, values.split(','))))
print(reduce(lambda a, b: a + int(b), values.split(','), 0))

I presented the choices in my order of preference. Comprehensions are very useful and something you need to know how to use. map() is like a one-trick-pony version of a comprehension. I don't find reduce() very useful.
