Question

In Python 3: Now, you will need two Python source files. One sender (send.py) and one receiver (receive.py). The sender will need establish a connection, channel and declare a queue. It will then need to send a message to the message queue once per second. You may use a while loop and the time.sleep function for this. The message should be something unique, like “My name is John Doe and I love Python! #” where is # is a running counter so you can see the message number. Each of the receivers, will need to establish a connection to the same queue, register a call back, and start consuming any messages received. When a message is received it should be output to standard out.

Below is the code for the given problem:-

SENDER.py

# doing using the RabbitMQ Libraries import pika import time # making the connection with the localhost connection = pika.BlockingConnection pika.ConnectionParameters (host='localhost')) # define the channel of connection channel = connection.channel() # declare the queue channel.queue_declare(queue='test') # using the for Loop to send a to 9 number for i in range(10): # publish the message channel.basic publish (exchange'', routing_key='test', body='My name is John Doe and I love Python! '+ str(i)) print(" Sent My name is John Doe and I love Python! ",i) # wait for 1 second time.sleep(1) # close the connection connection.close()

CODE:-

# doing using the RabbitMQ libraries

import pika

import time

# making the connection with the localhost

connection = pika.BlockingConnection(

    pika.ConnectionParameters(host='localhost'))

# define the channel of connection

channel = connection.channel()

# declare the queue

channel.queue_declare(queue='test')

# using the for loop to send 0 to 9 number

for i in range(10):

    # publish the message

    channel.basic_publish(exchange='', routing_key='test', body='My name is John Doe and I love Python! '+ str(i))

    print(" Sent My name is John Doe and I love Python! ",i)

    # wait for 1 second

    time.sleep(1)

# close the connection

connection.close()

RECEIVER.py

# doing using the RabbitMQ Libraries import pika # making the connection with the localhost connection = pika.BlockingConnection pika.ConnectionParameters (host='localhost')) # define the channel of connection channel = connection.channel() # declare the queue channel.queue_declare (queue='test') # callback function is called when the receiver receives something def callback(ch, method, properties, body): print("%r" % body) # define the consumer channel.basic consume queue='test', on_message_callback=callback, auto_ack=True), print("Waiting for messages. To exit press CTRL+C") # start receiving messages from sender channel.start_consuming()

CODE:-

# doing using the RabbitMQ libraries

import pika

# making the connection with the localhost

connection = pika.BlockingConnection(

    pika.ConnectionParameters(host='localhost'))

# define the channel of connection

channel = connection.channel()

# declare the queue

channel.queue_declare(queue='test')

# callback function is called when the receiver receives something

def callback(ch, method, properties, body):

    print("%r" % body)

# define the consumer

channel.basic_consume(

    queue='test', on_message_callback=callback, auto_ack=True)

print('Waiting for messages. To exit press CTRL+C')

# start receiving messages from sender

channel.start_consuming()

SAMPLE OUTPUT:-

sender

Sent My name is John Doe and I love Python! Sent My name is John Doe and I love Python! 1, Sent My name is John Doe and I love Python! 2 Sent My name is John Doe and I love Python! 3 Sent My name is John Doe and I love Python! 4, Sent My name is John Doe and I love Python! 5 Sent My name is John Doe and I love Python! 6 Sent My name is John Doe and I love Python! 7 Sent My name is John Doe and I love Python! 8 Sent My name is John Doe and I love Python! 9

receiver

] Waiting for messages. To exit press CTRL+C 'My name is John Doe and I love Python! O' My name is John Doe and I love Python! 1' My name is John Doe and I love Python! 2' 'My name is John Doe and I love Python! 3' 'My name is John Doe and I love Python! 4' My name is John Doe and I love Python! 5 'My name is John Doe and I love Python! 6' My name is John Doe and I love Python! 7' 'My name is John Doe and I love Python! 8' 'My name is John Doe and I love Python! 9'

NOTE:- I have added comments in the code for better understanding.

ALL THE BEST!
