An alternative way to accomplish the above using the ‘match’ method::

    >>> import re
    >>> pattern = re.compile("^.*:(? *)(\d+)$")
    >>> match = pattern.match("LINE: 235 : Primary Shelf Number (attempt 1): 1")
    >>> match.groups()
    ('1',)

Right. Always refer to the API documentation for the API you're
attempting to use.
