如何使用Python Socket模块发送消息？

# FileName: client.py import socketimport pandas as pd port = 8001  # 端口和上面一致host = "localhost"  # 服务器IP，这里服务器和客户端IP同一个 sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)for i in range(10):    sock.sendto(("Successful! Message %s! " % i).encode(), (host, port))# FileName: service.pydef socket_service():    port = 8001    sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)    sock.bind(("", port))  # 从给定的端口，从任何发送者，接收UDP数据报    print("Waiting for the port", port)     while True:        data, address = sock.recvfrom(1024)  # 接收一个报文为1024字节的数据报        print("Received:", data.decode(), "from", address)        if data.decode() == 'over':            break
