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
IntEnum constants:
AF_INET, AF_UNIX -- socket domains (first argument to socket() call)
SOCK_STREAM, SOCK_DGRAM, SOCK_RAW -- socket types (second argument)
Integer constants:
Many other constants may be defined; these may be used in calls to
the setsockopt() and getsockopt() methods.

Send a file until EOF is reached by using high-performance
os.sendfile() and return the total number of bytes which
were sent.
*file* must be a regular file object opened in binary mode.
If os.sendfile() is not available (e.g. Windows) or file is
not a regular file socket.send() will be used instead.
*offset* tells from where to start reading the file.
If specified, *count* is the total number of bytes to transmit
as opposed to sending the file until EOF is reached.
File position is updated on return or also in case of error in
which case file.tell() can be used to figure out the number of
bytes which were sent.
The socket must be of SOCK_STREAM type.
Non-blocking sockets are not supported.

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.
A host of '' or port 0 tells the OS to use the default.

Translate the host/port argument into a sequence of 5-tuples that contain
all the necessary arguments for creating a socket connected to that service.
host is a domain name, a string representation of an IPv4/v6 address or
None. port is a string service name such as 'http', a numeric port number or
None. By passing None as the value of host and port, you can pass NULL to
the underlying C API.
The family, type and proto arguments can be optionally specified in order to
narrow the list of addresses returned. Passing zero as a value for each of
these arguments selects the full range of results.
