Trouble is, there's an endless list of pattern expressions that can be useful.
IS_MATCH is pretty powerful, and should be in your bag of tricks (in fact,
IS_ALPHANUMERIC just calls IS_MATCH).
At the very least, consider that you might want a language-dependent
IS_LETTERS, or at least one that accepts the common alphabetic variants.
However, if you do that, do it this way:
IS_MATCH('[0-9]+', strict=True)
IS_MATCH('[a-zA-Z]+', strict=True)
strict=True forces a $ at the end of the regex. Or you can just include the $.
(IS_MATCH is already anchored at the beginning of the string.)
