def append( self, item ):
self.__toklist.append(item)<EOL>
Add single element to end of ParseResults list of elements.

Example::

    print(OneOrMore(Word(nums)).parseString("0 123 321")) # -> ['0', '123', '321']

    # use a parse action to compute the sum of the parsed integers, and add it to the end
    def append_sum(tokens):
        tokens.append(sum(map(int, tokens)))
    print(OneOrMore(Word(nums)).addParseAction(append_sum).parseString("0 123 321")) # -> ['0', '123', '321', 444]
