python实现tcp

以下是基于Python实现TCP的一些代码示例：

1. 服务器端代码示例：

import socket

# 创建TCP Socket
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 绑定IP和端口号
server_socket.bind(('localhost', 8888))

# 监听连接
server_socket.listen(1)
print('Waiting for client connection...')

while True:
    # 接受客户端连接
    client_socket, address = server_socket.accept()
    print(f'Connected by {address}')

    while True:
        # 接收客户端数据
        data = client_socket.recv(1024).decode('utf-8')
        if not data:
            break
        print(f'Received: {data}')

        # 发送响应数据
        response = f'Response: {data}'
        client_socket.send(response.encode('utf-8'))

    # 关闭客户端连接
    client_socket.close()

2. 客户端代码示例：

import socket

# 创建TCP Socket
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 连接服务器
client_socket.connect(('localhost', 8888))

while True:
    # 发送数据
    data = input('Enter message to send: ')
    client_socket.send(data.encode('utf-8'))

    # 接收响应数据
    response = client_socket.recv(1024).decode('utf-8')
    print(response)

# 关闭连接
client_socket.close()

以上是Python实现TCP的简单示例，可以根据实际需求进行修改。
