I have some use cases with: cut_at = some_str.find(sep) head, tail = some_str[:cut_at], some_str[cut_at:] and: cut_at = some_str.find(sep) head, tail = some_str[:cut_at], some_str[cut_at+offset:] # offset != len(sep)
So if partition() [or whatever it'll be called] could have an optional second argument that defines the width of the 'cut' made, I would be helped enormously. The default for this second argument would be len(sep), to preserve the current proposal.
Well, IMO, your example is much better written: import re rsep = re.compile(sep + '.'*offset) lst = re.split(resp, some_str, 1) head = lst[0] tail = lst[1] Or you want to have some "partition" method which accept regular expressions: head, sep, tail = some_str.partition(re.compile(sep+'.'*offset))
