Built-in Constants
|
|
==================
|
|
|
|
A small number of constants live in the built-in namespace. They are:
|
|
|
|
.. data:: False
|
|
|
|
The false value of the :class:`bool` type. Assignments to ``False``
|
|
are illegal and raise a :exc:`SyntaxError`.
|
|
|
|
|
|
.. data:: True
|
|
|
|
The true value of the :class:`bool` type. Assignments to ``True``
|
|
are illegal and raise a :exc:`SyntaxError`.
|
|
|
|
|
|
.. data:: None
|
|
|
|
The sole value of :attr:`types.NoneType`. ``None`` is frequently used to
|
|
represent the absence of a value, as when default arguments are not passed to a
|
|
function. Assignments to ``None`` are illegal and raise a :exc:`SyntaxError`.
|
|
|
|
|
|
.. data:: NotImplemented
|
|
|
|
Special value which can be returned by the "rich comparison" special methods
|
|
(:meth:`__eq__`, :meth:`__lt__`, and friends), to indicate that the comparison
|
|
is not implemented with respect to the other type.
|
|
|
|
|
|
.. data:: Ellipsis
|
|
|
|
The same as ``...``. Special value used mostly in conjunction with extended
|
|
slicing syntax for user-defined container data types.
|
|
|
|
|
|
.. data:: __debug__
|
|
|
|
This constant is true if Python was not started with an :option:`-O` option.
|
|
See also the :keyword:`assert` statement.
|
|
|
|
|
|
.. note::
|
|
|
|
The names :data:`None`, :data:`False`, :data:`True` and :data:`__debug__`
|
|
cannot be reassigned (assignments to them, even as an attribute name, raise
|
|
:exc:`SyntaxError`), so they can be considered "true" constants.
|
|
|
|
|
|
Constants added by the :mod:`site` module
|
|
-----------------------------------------
|
|
|
|
The :mod:`site` module (which is imported automatically during startup, except
|
|
if the :option:`-S` command-line option is given) adds several constants to the
|
|
built-in namespace. They are useful for the interactive interpreter shell and
|
|
should not be used in programs.
|
|
|
|
.. data:: quit(code=None)
|
|
exit(code=None)
|
|
|
|
Objects that when printed, print a message like "Use quit() or Ctrl-D
|
|
(i.e. EOF) to exit", and when called, raise :exc:`SystemExit` with the
|
|
specified exit code.
|
|
|
|
.. data:: copyright
|
|
license
|
|
credits
|
|
|
|
Objects that when printed, print a message like "Type license() to see the
|
|
full license text", and when called, display the corresponding text in a
|
|
pager-like fashion (one screen at a time).
