Help with converting strings to arrays

[ThiefOfTime]

Let us assume you can not be sure that each item is an integer and all are seperate through a comma.
The simplest solution assuming that each is an integer is:

row_arr = row[0].split(',')
row_arr = [int(value) for value in row_arr]

If you can not be sure that each is a string, you should consider regex:

import re
your_regex = re.compile('([0-9]+)')
row_array = row_array[0].split(',')
row_array = [int(your_regex.match(value).group(1)) for value in row_array if your_regex.match(value) is not None]

what this does is to check if you string is matching this pattern, which defines each number greater than 0. If you find a string like "a" your regex will return None and you may skip it :)
