=== TCP客户端/服务端示例 ===
以下Python示例展示基础TCP通信：

==== 服务端代码 ====
<syntaxhighlight lang="python">
import socket

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind(('0.0.0.0', 8080))
server_socket.listen(1)

print("等待连接...")
conn, addr = server_socket.accept()
print(f"连接来自: {addr}")

data = conn.recv(1024)
print(f"收到数据: {data.decode()}")
conn.sendall(b"Message received")
conn.close()
</syntaxhighlight>

==== 客户端代码 ====
<syntaxhighlight lang="python">
import socket

client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect(('127.0.0.1', 8080))

client_socket.sendall(b"Hello Server!")
response = client_socket.recv(1024)
print(f"服务端响应: {response.decode()}")
client_socket.close()
</syntaxhighlight>

==== 执行流程 ====
1. 启动服务端后进入监听状态
2. 客户端连接并发送"Hello Server!"
3. 服务端回应"Message received"
4. 客户端打印响应后关闭连接
