coroutine read(n=-1) Read up to n bytes. If n is not provided, or set to -1, read until EOF and return all read bytes. If the EOF was received and the internal buffer is empty, return an empty bytes object. This method is a coroutine.

load_module(name=None) Concrete implementation of importlib.abc.Loader.load_module() where specifying the name of the module to load is optional.

socket.getsockname() Return the socket’s own address. This is useful to find out the port number of an IPv4/v6 socket, for instance. (The format of the address returned depends on the address family — see above.)

get() Remove and return an item from the queue.

SSLSocket.shared_ciphers() Return the list of ciphers shared by the client during the handshake. Each entry of the returned list is a three-value tuple containing the name of the cipher, the version of the SSL protocol that defines its use, and the number of secret bits the cipher uses. shared_ciphers() returns None if no connection has been established or the socket is a client socket. New in version 3.5.

unicodedata.bidirectional(chr) Returns the bidirectional class assigned to the character chr as string. If no such value is defined, an empty string is returned.

exception SystemError Raised when the interpreter finds an internal error, but the situation does not look so serious to cause it to abandon all hope. The associated value is a string indicating what went wrong (in low-level terms). You should report this to the author or maintainer of your Python interpreter. Be sure to report the version of the Python interpreter (sys.version; it is also printed at the start of an interactive Python session), the exact error message (the exception’s associ

exception tarfile.CompressionError Is raised when a compression method is not supported or when the data cannot be decoded properly.

errors A list containing 2-tuples of TestCase instances and strings holding formatted tracebacks. Each tuple represents a test which raised an unexpected exception.

listen(backlog) Listen for connections made to the socket. The backlog argument specifies the maximum number of queued connections and should be at least 1; the maximum value is system-dependent (usually 5).
