Z7e+Z8e-Z9e/Z:dS)^�ParseResultsaStructured parse results, to provide multiple means of access to
    the parsed data:

    - as a list (``len(results)``)
    - by list index (``results[0], results[1]``, etc.)
    - by attribute (``results.<results_name>`` - see :class:`ParserElement.set_results_name`)

    Example::

        integer = Word(nums)
        date_str = (integer.set_results_name("year") + '/'
                    + integer.set_results_name("month") + '/'
                    + integer.set_results_name("day"))
        # equivalent form:
        # date_str = (integer("year") + '/'
        #             + integer("month") + '/'
        #             + integer("day"))

        # parse_string returns a ParseResults object
        result = date_str.parse_string("1999/12/31")

        def test(s, fn=repr):
            print("{} -> {}".format(s, fn(eval(s))))
        test("list(result)")
        test("result[0]")
        test("result['month']")
        test("result.day")
        test("'month' in result")
        test("'minutes' in result")
        test("result.dump()", str)

    prints::

        list(result) -> ['1999', '/', '12', '/', '31']
        result[0] -> '1999'
        result['month'] -> '12'
        result.day -> '31'
        'month' in result -> True
        'minutes' in result -> False
        result.dump() -> ['1999', '/', '12', '/', '31']

ZdS)zParseResults.Lista�
        Simple wrapper class to distinguish parsed list results that should be preserved
        as actual Python lists, instead of being converted to :class:`ParseResults`:

            LBRACK, RBRACK = map(pp.Suppress, "[]")
            element = pp.Forward()
            item = ppc.integer
            element_list = LBRACK + pp.delimited_list(element) + RBRACK

            # add parse actions to convert from ParseResults to actual Python collection types
            def as_python_list(t):
                return pp.ParseResults.List(t.as_list())
            element_list.add_parse_action(as_python_list)

            element <<= item | element_list

            element.run_tests('''
                100
                [2,3,4]
                [[2, 1],3,4]
                [(2, 1),3,4]
                (2,3,4)
                ''', post_parse=lambda s, r: (r[0], type(r[0])))

        prints:

            100
            (100, <class 'int'>)

            [2,3,4]
            ([2, 3, 4], <class 'list'>)

            [[2, 1],3,4]
            ([[2, 1], 3, 4], <class 'list'>)

        (Used internally by :class:`Group` when `aslist=True`.)

        Removes and returns item at specified index (default= ``last``).
        Supports both ``list`` and ``dict`` semantics for ``pop()``. If
        passed no argument or an integer argument, it will use ``list``
        semantics and pop tokens from the list of parsed tokens. If passed
        a non-integer argument (most likely a string), it will use ``dict``
        semantics and pop the corresponding value from any defined results
        names. A second default return value argument is supported, just as in
        ``dict.pop()``.

        Example::

            numlist = Word(nums)[...]
            print(numlist.parse_string("0 123 321")) # -> ['0', '123', '321']

            def remove_first(tokens):
                tokens.pop(0)
            numlist.add_parse_action(remove_first)
            print(numlist.parse_string("0 123 321")) # -> ['123', '321']

            label = Word(alphas)
            patt = label("LABEL") + OneOrMore(Word(nums))
            print(patt.parse_string("AAB 123 321").dump())

            # Use pop() in a parse action to remove named result (note that corresponding value is not
            # removed from list form of results)
            def remove_LABEL(tokens):
                tokens.pop("LABEL")
                return tokens
            patt.add_parse_action(remove_LABEL)
            print(patt.parse_string("AAB 123 321").dump())

        prints::

            ['AAB', '123', '321']
            - LABEL: AAB

            ['AAB', '123', '321']

        Returns named result matching the given key, or if there is no

        ``default_value`` is specified.

        Similar to ``dict.get()``.

        Example::

        Diagnostic method for listing out the contents of
        a :class:`ParseResults`. Accepts an optional ``indent`` argument so
        that this string can be embedded in a nested display of other data.

        Example::

            integer = Word(nums)
            date_str = integer("year") + '/' + integer("month") + '/' + integer("day")

            result = date_str.parse_string('12/31/1999')
            print(result.dump())

        prints::

            ['12', '/', '31', '/', '1999']
            - day: 1999
            - month: 31
            - year: 12

        Pretty-printer for parsed results as a list, using the
        `pprint <https://docs.python.org/3/library/pprint.html>`_ module.
        Accepts additional positional or keyword args as defined for
        `pprint.pprint <https://docs.python.org/3/library/pprint.html#pprint.pprint>`_ .

        Example::

            ident = Word(alphas, alphanums)
            num = Word(nums)
            func = Forward()
            term = ident | num | Group('(' + func + ')')
            func <<= ident + Group(Optional(delimited_list(term)))
            result = func.parse_string("fna a,b,(fnb c,d,200),100")
            result.pprint(width=40)

        prints::

            ['fna',
             ['a',
              'b',
              ['(', 'fnb', ['c', 'd', '200'], ')'],
              '100']]

        Helper classmethod to construct a ``ParseResults`` from a ``dict``, preserving the
        name-value relations as results names. If an optional ``name`` argument is
        given, a nested ``ParseResults`` will be returned.
