how can i make a sum in a line of numbers in python?

Question

i'm in trouble trying to calculate and appear the sum of a series of numbers in lines. it should be like this:

32565854 SUM: 38

65985456 SUM: 48

17984956 SUM: 49

Answer 1

you can turn the line into string and then:

sum(map(int, '32565854'))

with a file:

with open('input.txt') as f:
    for line in f:
        line = line.strip()
        print line + ' ' + str(sum(map(int, line)))
