如何从我的本地计算机（client.py）发送一个简单的 UDP 消息到远程服务器 pythonanywhere(server.py)

Question

I want to send a simple UDP message from my local computer(client.py) to a remote server pythonanywhere(server.py). I don't actually know if I'm doing it right, or maybe what I did is not a good practice. How can I do that? I'm still a beginner in socket programming.

client.py(local computer)

import socket

ip = "<insert ip here>"
port = 9999
Message = "Hello, Server"

clientSock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
clientSock.sendto(Message.encode('utf-8'), (ip, port))

server.py(pythonanywhere)

import socket

ip = "<insert ip here>"
port = 9999

serverSock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

serverSock.bind((ip, port))

while True:
    data, addr = serverSock.recvfrom(4096)
    print("Message: ", data)

You cannot run a udp socket server on PythonAnywhere. PythonAnywhere does not route arbitrary network traffic to the machines where you would be running the server code.
