On Unix, it supports IP (Internet Protocol) and Unix domain sockets. On other systems, it only supports IP. Functions specific for a socket are available as methods of the socket object. Functions: socket() -- create a new socket object socketpair() -- create a pair of new socket objects [*] fromfd() -- create a socket object from an open file descriptor [*] fromshare() -- create a socket object from data received from socket.share() [*] gethostname() -- return the current hostname gethostbyname() -- map a hostname to its IP number gethostbyaddr() -- map an IP number or hostname to DNS info getservbyname() -- map a service name and a protocol name to a port number getprotobyname() -- map a protocol name (e.g. 'tcp') to a number ntohs(), ntohl() -- convert 16, 32 bit int from network to host byte order htons(), htonl() -- convert 16, 32 bit int from host to network byte order inet_aton() -- convert IP addr string (123.45.67.89) to 32-bit packed format inet_ntoa() -- convert 32-bit packed format IP to string (123.45.67.89) socket.getdefaulttimeout() -- get the default timeout value socket.setdefaulttimeout() -- set the default timeout value create_connection() -- connects to an address, with an optional timeout and optional source address. [*] not available on all platforms! Special objects: SocketType -- type object for socket objects error -- exception raised for I/O errors has_ipv6 -- boolean value indicating if IPv6 is supported Integer constants: AF_INET, AF_UNIX -- socket domains (first argument to socket() call) SOCK_STREAM, SOCK_DGRAM, SOCK_RAW -- socket types (second argument) Many other constants may be defined; these may be used in calls to the setsockopt() and getsockopt() methods. i N( u *u EBADFi u EAGAINi u EWOULDBLOCKu getfqdnu create_connectionu winu The operation was interrupted.i' u A bad file handle was passed.i' u Permission denied.i ' u!

Convenience function. Connect to *address* (a 2-tuple ``(host, port)``) and return the socket object. Passing the optional *timeout* parameter will set the timeout on the socket instance before attempting to connect. If no *timeout* is supplied, the global default timeout setting returned by :func:`getdefaulttimeout` is used. If *source_address* is set it must be a tuple of (host, port) for the socket to bind as a source address before making the connection. An host of '' or port 0 tells the OS to use the default. i Nu! getaddrinfo returns an empty list( u Noneu getaddrinfou SOCK_STREAMu socketu _GLOBAL_DEFAULT_TIMEOUTu settimeoutu bindu connectu erroru close( u addressu timeoutu source_addressu hostu portu erru resu afu socktypeu protou canonnameu sau socku _( ( u+ /opt/alt/python33/lib64/python3.3/socket.pyu create_connection� s( $ (" u __doc__u _socketu osu sysu iou errnou ImportErroru Noneu getattru EBADFu EAGAINu EWOULDBLOCKu __all__u extendu _get_exports_listu socketu _realsocketu platformu loweru startswithu errorTabu appendu fromfdu hasattru fromshareu SOCK_STREAMu socketpairu _blocking_errnosu RawIOBaseu SocketIOu getfqdnu objectu _GLOBAL_DEFAULT_TIMEOUTu create_connection( ( ( u+ /opt/alt/python33/lib64/python3.3/socket.pyu <module>- sV $ ~ w
