如果python中没有传递参数，如何发送消息

print("Hello, World!")

import logging

logging.basicConfig(level=logging.INFO)
logging.info("Hello, World!")

import socket

HOST = 'localhost'
PORT = 12345

with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
    s.connect((HOST, PORT))
    s.sendall(b'Hello, World!')

import pika

connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
channel = connection.channel()

channel.queue_declare(queue='hello')
channel.basic_publish(exchange='', routing_key='hello', body='Hello, World!')

connection.close()
