def print_keyword_args(**kwargs):
    # kwargs is a dict of the keyword args passed to the function
    for key, value in kwargs.iteritems():
        print "%s = %s" % (key, value)
        # output:
        # first_name = Bobby
        # last_name = Smith

kwargs = {'first_name': 'Bobby', 'last_name': 'Smith'}
