4. Built-in Constants — Python v2.6.2 documentation

4. Built-in Constants¶

A small number of constants live in the built-in namespace. They are:

False¶

The false value of the bool type.

New in version 2.3.

True¶

The true value of the bool type.

New in version 2.3.

None¶

The sole value of types.NoneType. None is frequently used to represent the absence of a value, as when default arguments are not passed to a function.

Changed in version 2.4: Assignments to None are illegal and raise a SyntaxError.

NotImplemented¶
Special value which can be returned by the “rich comparison” special methods (__eq__(), __lt__(), and friends), to indicate that the comparison is not implemented with respect to the other type.
Ellipsis¶
Special value used in conjunction with extended slicing syntax.
__debug__¶
This constant is true if Python was not started with an -O option. Assignments to __debug__ are illegal and raise a SyntaxError. See also the assert statement.

4.1. Constants added by the site module¶

The site module (which is imported automatically during startup, except if the -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.

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 SystemExit with the specified exit code, and when .
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).
