operator.is_(a, b) Return a is b. Tests object identity.

readline.set_completion_display_matches_hook([function]) Set or remove the completion display function. If function is specified, it will be used as the new completion display function; if omitted or None, any completion display function already installed is removed. This sets or clears the rl_completion_display_matches_hook callback in the underlying library. The completion display function is called as function(substitution, [matches], longest_match_length) once each time matches need to b

multiprocessing.Pipe([duplex]) Returns a pair (conn1, conn2) of Connection objects representing the ends of a pipe. If duplex is True (the default) then the pipe is bidirectional. If duplex is False then the pipe is unidirectional: conn1 can only be used for receiving messages and conn2 can only be used for sending messages.

encoding The name of the encoding that raised the error.

Queue.empty() Return True if the queue is empty, False otherwise. If empty() returns True it doesn’t guarantee that a subsequent call to put() will not block. Similarly, if empty() returns False it doesn’t guarantee that a subsequent call to get() will not block.

info() Return a formatted multi-line string with detailed information about the code object, like code_info().

aifc.aiff() Create an AIFF file. The default is that an AIFF-C file is created, unless the name of the file ends in '.aiff' in which case the default is an AIFF file.

exception queue.Empty Exception raised when non-blocking get() (or get_nowait()) is called on a Queue object which is empty.

SSLSocket.server_side A boolean which is True for server-side sockets and False for client-side sockets. New in version 3.2.

itertools.accumulate(iterable[, func]) Make an iterator that returns accumulated sums, or accumulated results of other binary functions (specified via the optional func argument). If func is supplied, it should be a function of two arguments. Elements of the input iterable may be any type that can be accepted as arguments to func. (For example, with the default operation of addition, elements may be any addable type including Decimal or Fraction.) If the input iterable is empty, the output i
