用python写一个服务端tcp通信代码

我可以回答这个问题。以下是一个简单的Python TCP服务器代码示例：

import socket

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

# 绑定IP地址和端口号
server_socket.bind(('127.0.0.1', 8888))

# 监听客户端连接
server_socket.listen(5)

print('服务器已启动，等待客户端连接...')

while True:
    # 接受客户端连接
    client_socket, client_address = server_socket.accept()

    print('客户端已连接：', client_address)

    # 接收客户端数据
    data = client_socket.recv(1024)

    # 处理客户端请求
    response = 'Hello, ' + data.decode()

    # 发送响应数据给客户端
    client_socket.send(response.encode())

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

这个代码创建了一个TCP服务器，绑定在本地IP地址127.0.0.1和端口号8888上。当有客户端连接时，服务器会接收客户端发送的数据，并返回一个简单的响应。

用Python写一个TCP Socket通信 服务端

import socket

HOST = '127.0.0.1' # 本地主机IP
PORT = 8000 # 监听的端口号

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # 创建socket对象
server_socket.bind((HOST, PORT)) # 绑定端口号
server_socket.listen(1) # 监听端口，最大连接数为1

print('Server started listening on {}:{}'.format(HOST, PORT))

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

data = client_socket.recv(1024).decode() # 接收客户端发送的数据
print('Received message:', data)

response = 'Hello, client! I have received your message: {}'.format(data)
client_socket.sendall(response.encode()) # 发送响应数据给客户端

client_socket.close() # 关闭客户端连接

用python分别写tcp通信的服务端和客户端代码

当然可以，以下是Python的TCP通信服务端和客户端代码供您参考：

服务端代码：

import socket

HOST = ''
PORT = 8888

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind((HOST, PORT))
server_socket.listen(1)

while True:
client_socket, client_address = server_socket.accept()
print('Incoming connection from:', client_address)
while True:
data = client_socket.recv(1024)
if not data:
break
client_socket.sendall(data)
client_socket.close()

客户端代码：

import socket

HOST = '127.0.0.1'
PORT = 8888

client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect((HOST, PORT))

client_socket.sendall(b'Hello, server!')
data = client_socket.recv(1024)
print('Received:', data.decode())

client_socket.sendall(b'How are you?')
data = client_socket.recv(1024)
print('Received:', data.decode())

client_socket.sendall(b'Goodbye!')
data = client_socket.recv(1024)
print('Received:', data.decode())

client_socket.close()
