Interesting thing with Pipe

gistfile1.py

from multiprocessing import Pool, Pipe, Process

def work(process_name, pipe):	
	while True:
		print("%s Start w8!" % process_name)
		data = pipe.recv()
		print("%s You sent %s" % (process_name, data))
	

if __name__ == "__main__":
	parent, child = Pipe()
	p1 = Process(target=work, args=("P1", child,))
	p1.start()

	p2 = Process(target=work, args=("P2", child,))
	p2.start()
	while True:
		try:
			data = raw_input()
			parent.send(data)
		except KeyboardInterrupt:
			print("On KeyboardInterrupt")
			child.close()
			parent.close()
			exit(0)
