下面是一个简单的使用TCP/IP协议进行通信的Python编程案例:
```python
import socket
# 创建一个TCP/IP套接字
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# 绑定套接字到指定的IP地址和端口号
server_address = ('localhost', 8888)
print('启动服务器在 %s 端口 %s 地址上' % server_address)
sock.bind(server_address)
# 监听传入的连接
sock.listen(1)
while True:
print('等待连接...')
connection, client_address = sock.accept()
try:
print('连接来自:', client_address)
# 接收数据
data = connection.recv(1024)
print('接收到的数据:', data.decode())
# 发送响应
response = 'Hello, client!'
connection.sendall(response.encode())
finally:
# 关闭连接
connection.close()
```
