If this token doesn't match the given token type. *values* is a list of possible values for this token. The values are OR'ed together so if only one of the values matches ``True`` is returned. Except for keyword tokens the comparison is case-sensitive. For convenience it's OK to pass in a single string. If *regex* is ``True`` (default is ``False``) the given values are treated as regular expressions.
