Python split help

Hey guys, I'm trying to split a string at \n but there is a \n at the end of the string. It is creating an empty list and I'm getting an error when I want to loop through it. Can anyone give me a fix to this problem?

def read_coords(s):    split_string = ''     alive_cells = []         split_string = s.split('\n')        for x in range(len(split_string)):        for y in range(len(split_string)):            if split_string[x][y] == 'O':                alive_cells.append('(%d,%d)' %(x, y))        read_coords("O..\n.OO\n")

Could you change the range of the for loop to len(split_string) - 1?

No I don't think that works. Basically what's happening is it is creating a new string at the final \n. Is there any way I can stop it from doing that?

After splitting add a check to see if the last element is valid, if it isn't delete it.

if not split_string[-1]:   split_string.pop()

edit: or add a call to strip before splitting.
