socket(family=AF_INET, type=SOCK_STREAM, proto=0) -> socket object socket(family=-1, type=-1, proto=-1, fileno=None) -> socket object Open a socket of the given type. The family argument specifies the address family; it defaults to AF_INET. The type argument specifies whether this is a stream (SOCK_STREAM, this is the default) or datagram (SOCK_DGRAM) socket. The protocol argument defaults to 0, specifying the default protocol. Keyword arguments are accepted. The socket is created as non-inheritable. When a fileno is passed in, family, type and proto are auto-detected, unless they are explicitly set. A socket object represents one endpoint of a network connection. Methods of socket objects (keyword arguments not allowed): _accept() -- accept connection, returning new socket fd and client address bind(addr) -- bind the socket to a local address close() -- close the socket connect(addr) -- connect the socket to a remote address connect_ex(addr) -- connect, return an error code instead of an exception dup() -- return a new socket fd duplicated from fileno() fileno() -- return underlying file descriptor getpeername() -- return remote address [*] getsockname() -- return local address getsockopt(level, optname[, buflen]) -- get socket options gettimeout() -- return timeout or None listen([n]) -- start listening for incoming connections recv(buflen[, flags]) -- receive data recv_into(buffer[, nbytes[, flags]]) -- receive data (into a buffer) recvfrom(buflen[, flags]) -- receive data and sender's address recvfrom_into(buffer[, nbytes, [, flags]]) -- receive data and sender's address (into a buffer) sendall(data[, flags]) -- send all data send(data[, flags]) -- send data, may not send all of it sendto(data[, flags], addr) -- send data to a given address setblocking(bool) -- set or clear the blocking I/O flag getblocking() -- return True if socket is blocking, False if non-blocking setsockopt(level, optname, value[, optlen]) -- set socket options settimeout(None | float) -- set or clear the timeout shutdown(how) -- shut down traffic in one or both directions [*] not available on all platforms!
