[Tutor] Summing across a row

[Kent Johnson]

 >>> line = '1, 2, 3, 4'  # original input
 >>> line.split(', ')  # split it up into fields
['1', '2', '3', '4']

 >>> map(int, line.split(', '))  # convert the field values to integers
[1, 2, 3, 4]

 >>> [int(x) for x in line.split(', ')]  # another way to convert to integers
[1, 2, 3, 4]

 >>> sum(map(int, line.split(', ')))  # Add them all up
10
