re module: search() vs. match() section should mention fullmatch() #98906
Description
The docs at https://docs.python.org/3/library/re.html#search-vs-match start with
Python offers two different primitive operations based on regular expressions: re.match() checks for a match only at the beginning of the string, while re.search() checks for a match anywhere in the string (this is what Perl does by default).
but there has been re.fullmatch() since Python 3.4. I believe the third method should be mentioned and should get its own examples as well.

That seems like a good idea. Just this week I was looking at search vs. match, and completely forgot about fullmatch.

Great that there's interest enhancing this! One thing to decide is should the section header be changed or not. Mentioning only search and match when there's also fullmatch would be odd, but the change would break possible internal and external links to this section. Internal links can be fixed as part of this change, though, and external ones can be preserved by adding an explicit link target with the old name. What approach has been used in this kind of situations earlier?

I think it's fine to keep the section name, especially as fullmatch is a variant of
match().rhettinger commentedon Nov 5, 2022

I would also like
fullmatchbecome better known.That said, a cross-reference between the two entries doesn't make sense. The entries are already adjacent to one another. And we don't want to get into the business of stylistic nudging by having one feature "advertise" another.
Instead, it would be better to beef up the examples to show off
fullmatch. Also the text formatchandfullmatchshould be expanded to draw a distinction between the them. We already have verbiage about being different from a zero-length match. There should be further wording to highlight howmatchandfullmatchdiffer from one another.GH-98906 ```re``` module: ```search() vs. match()``` section should m…
