end([group])

The end operation behaves exactly the same as start, except that it returns the end of the substring matched by the group:

>>> pattern = re.compile(r"(?P<first>\w+) (?P<second>\w+)?") >>> match = pattern.search("Hello⇢") >>> match.end (1) 5

span([group])

It's an operation that gives you a tuple with the values from start and end. This operation is often used in text editors to locate and highlight a search. The following code is an example of this operation:

>>> pattern = re.compile(r"(?P<first>\w+) (?P<second>\w+)?") >>> match = pattern.search("Hello⇢") >>> match.span(1) (0, 5)
