Implementing Internet Communication : socket « Network « Python Tutorial

# Protocol Families for Python Sockets
# Family      Description
# AF_INET     Ipv4 protocols (TCP, UDP)
# AF_INET6    Ipv6 protocols (TCP, UDP)
# AF_UNIX     Unix domain protocols

# Socket Types for Python Sockets

# Type              Description
# SOCK_STREAM       Opens an existing file for reading.
# SOCK_DGRAM        Opens a file for writing. 
# SOCK_RAW          Opens an existing file for updating, keeping the existing contents intact.
# SOCK_RDM          Opens a file for both reading and writing. The existing contents are kept intact.
# SOCK_SEQPACKET    Opens a file for both writing and reading. The existing contents are deleted.
