#78825 — help with regex

I want the last "1"
I can't this to work:

>>> pattern=re.compile( "(\d+)$" )
>>> match=pattern.match( "LINE: 235 : Primary Shelf Number (attempt 1): 1")
>>> print match.group()

>>> pattern = re.compile("(\d+)$")
>>> match = pattern.search( "LINE: 235 : Primary Shelf Number (attempt 1): 
1")
>>> match.group()
'1'

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.
