Connection error for RabbitMQ

Question

I am completely new to MQs and pika.

When I am trying to execute this code(server code) I am getting errors: (I am getting same error for receiver code also.)

import pika
connection = pika.BlockingConnection(pika.ConnectionParameters(
     host="localhost:5672"))
channel = connection.channel()
channel.queue_declare(queue='hello')
channel.basic_publish(exchange='',
                  routing_key='hello',
                  body='Hello World!')
print(" [x] Sent 'Hello World!'")
connection.close()

Error :

Traceback (most recent call last):
File "D:\Workspace\Luna_WS\MQ\RabbitMQ\Sample\Src\Sample.py", line 10, in <module>
host="localhost:5672"))
File "C:\Python34\lib\site-packages\pika\adapters\blocking_connection.py", line 339, in __init__

pika.exceptions.ConnectionClosed

I had installed: (using windows 7, 32 bit)

pikka package - pika-0.10.0-py2.py3-none-any.whl

Erlang - esl-erlang_18.2-1-windows_i386

RabbitMq server - rabbitmq-server-3.6.0

Try splitting the host into separate host and port connection parameters:

connection = pika.BlockingConnection(
                 pika.ConnectionParameters(host="localhost", port=5672))
