Socket Example3#
Question#
Different types of socket constants.
Solution#
import socket
def get_constants(prefix):
"""Create a dictionary mapping socket module constants to their names."""
return dict( (getattr(socket, n), n)
for n in dir(socket)
if n.startswith(prefix)
)
families = get_constants('AF_')
print(families)
types = get_constants('SOCK_')
print(types)
protocols = get_constants('IPPROTO_')
print(protocols)
for response in socket.getaddrinfo('endhiroid.blogspot.com', 'http',
socket.AF_INET, # family
socket.SOCK_STREAM, # socktype
socket.IPPROTO_TCP, # protocol
socket.AI_CANONNAME, # flags
):
# Unpack the response tuple
family, socktype, proto, canonname, sockaddr = response
print('Family :', families[family])
print('Type :', types[socktype])
print('Protocol :', protocols[proto])
print('Canonical name:', canonname)
print('Socket address:', sockaddr)
