class collections.abc.Hashable class collections.abc.Sized class collections.abc.Callable ABCs for classes that provide respectively the methods __contains__(), __hash__(), __len__(), and __call__().

update(arg) Parameter arg should be a key-to-message mapping or an iterable of (key, message) pairs. Updates the mailbox so that, for each given key and message, the message corresponding to key is set to message as if by using __setitem__(). As with __setitem__(), each key must already correspond to a message in the mailbox or else a KeyError exception will be raised, so in general it is incorrect for arg to be a Mailbox instance. Note Unlike with dictionaries, keyword arguments are not su

pow(x, y[, z]) Return x to the power y; if z is present, return x to the power y, modulo z (computed more efficiently than pow(x, y) % z). The two-argument form pow(x, y) is equivalent to using the power operator: x**y. The arguments must have numeric types. With mixed operand types, the coercion rules for binary arithmetic operators apply. For int operands, the result has the same type as the operands (after coercion) unless the second argument is negative; in that case, all arguments are c

InputSource.getSystemId() Returns the system identifier of this InputSource.

@typing.no_type_check_decorator(decorator) Decorator to give another decorator the no_type_check() effect. This wraps the decorator with something that wraps the decorated function in no_type_check().

exception ossaudiodev.OSSAudioError This exception is raised on certain errors. The argument is a string describing what went wrong. (If ossaudiodev receives an error from a system call such as open(), write(), or ioctl(), it raises OSError. Errors detected directly by ossaudiodev result in OSSAudioError.) (For backwards compatibility, the exception class is also available as ossaudiodev.error.)

stat.filemode(mode) Convert a file’s mode to a string of the form ‘-rwxrwxrwx’. New in version 3.3. Changed in version 3.4: The function supports S_IFDOOR, S_IFPORT and S_IFWHT.

broadcast_address The broadcast address for the network. Packets sent to the broadcast address should be received by every host on the network.

class socketserver.ThreadingTCPServer class socketserver.ThreadingUDPServer These classes are pre-defined using the mix-in classes.

xmlparser.ProcessingInstructionHandler(target, data) Called for every processing instruction.
