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']
- day: '31'

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, "[]")

item = ppc.integer
element_list = LBRACK + pp.delimited_list(element) + RBRACK
# add parse actions to convert from ParseResults to actual Python collection types

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") + Word(nums)[1, ...]
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
such name, then returns the given ``default_value`` or ``None`` if no
``default_value`` is specified.
Similar to ``dict.get()``.
Example::
integer = Word(nums)
date_str = integer("year") + '/' + integer("month") + '/' + integer("day")
result = date_str.parse_string("1999/12/31")
print(result.get("year")) # -> '1999'

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

Example::
