	import socket

	host = "foo.bar.com"
	port = 12345
	msg = "Hello"
	buffersize = 4096

	## Create TCP socket
	client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
	## Connect to the host
	client.connect((host, port))
	## Send some data
	client.send(msg)
	## Recieve some data
	response = client.recv(buffersize)

	## Create UDP socket
	client = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
	## UDP is a connectionless protocol so no need to call connect() beforehand
	## Send some data
	client.sendto(msg, (host, port))
	## Recieve some data
	recvdata, addr = client.recvfrom(buffersize) #recvfrom returns both data and the detail of the remote host and port, AKA address
