[issue21002] _sre.SRE_Scanner object should have a fullmatch() method

Serhiy Storchaka added the comment: I concur with David. The SRE_Scanner object is not public. Its search() method is used for implementing finditer(). Its match() method could be useful for implementing a functional equivalent of \G in Perl. But I do not know a use case for its fullmatch()

Lewis Gaul added the comment: Scanner is not documented in CPython's own re documentation: https://docs.python.org/3/library/re.html#regular-expression-objects, so I'd say there's no obligation to maintain consistency with public APIs. Is anyone able to make a call on whether this issue

Gareth Gouldstone added the comment: Scanner may not be a public interface but it is widely documented, not least on page 67 of the O'reilly Python Cookbook. Even if Scanner is not made public, then surely it should maintain consistency with the public interfaces? -- versions:

New submission from Gareth Gouldstone: I believe that the SRE_Scanner object should have a .fullmatch() method for consistency with other re pattern-matching behaviour. rex = re.compile('([^\\W\\d_]{1,2}[0-9]{1,2}[^\\d\\W_]?)[ \\t]*([0-9][^\\d\\W_]{2})') rex.scanner('bn20bs')
