It works as of now it just takes way to long to operate, probably because it is several different regex subs. They are as follow: tempString = ','.join(str(n) for n in coords) tempString = re.sub(',{2,6}', '_', tempString) tempString = re.sub("[^0-9\-\.\_]", "...
I found this generator based approach more satisfying: def split_keep(string, sep): """Usage: >>> list(split_keep("a.b.c.d", ".")) ['a.', 'b.', 'c.', 'd'] """ start = 0 while True: end = string.find(sep, start) + 1 if end == 0: break yield string[start:...
