Rearrange the blocks of Python code below in the correct order. It's similar to part of the the chat program that you wrote in Lesson 1. The lines beginning with a hash (#) are comments to help understand what each code block does.
#decide if the Raspberry Pi will be a server (no IP address given) or a client
if (len(sys.argv) >= 2):
network.call(sys.argv[1], whenHearCall=heard)
else:
network.wait(whenHearCall=heard)#a function that prints a message
def heard(phrase):
print("them:" + phrase)#The main part of the program - send a message
while network.isConnected():
#phrase = raw_input() #python2
phrase = input() # python3
print("me:" + phrase)
network.say(phrase)#import modules so that you can use functions from other programs
import network
