better try things yourself before suggesting them to others:

 >>> my_string = '0,1,2,3'
 >>> my_lst=my_string.split(",")
 >>> leng = len(my_lst)
 >>> b=sum(my_lst)
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for +: 'int' and 'str'

This is exactly why the OP had to come up with his comprehension solution.
