如何使用Python中的socket编程进行数据通信

import socket

# 创建TCP socket对象
tcp_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 创建UDP socket对象
udp_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# 设置服务器的IP地址和端口号
server_address = ('127.0.0.1', 8888)

# 连接服务器
tcp_socket.connect(server_address)

# 发送数据给服务器
tcp_socket.send('Hello Server!'.encode())

# 接收服务器返回的数据
data = tcp_socket.recv(1024).decode()
print('Received from server:', data)

# 关闭TCP连接
tcp_socket.close()

import socket

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

# 设置服务器的IP地址和端口号
server_address = ('127.0.0.1', 8888)

# 绑定地址和端口号
server_socket.bind(server_address)

# 监听客户端连接
server_socket.listen(1)
print('Waiting for connection...')

# 等待客户端连接
client_socket, client_address = server_socket.accept()
print('Accepted connection from:', client_address)

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

# 向客户端发送数据
client_socket.send('Hello Client!'.encode())

# 关闭连接
client_socket.close()
server_socket.close()

import socket

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

# 设置服务器的IP地址和端口号
server_address = ('127.0.0.1', 8888)

# 连接服务器
client_socket.connect(server_address)

# 发送数据给服务器
client_socket.send('Hello Server!'.encode())

# 接收服务器返回的数据
data = client_socket.recv(1024).decode()
print('Received from server:', data)

# 关闭连接
client_socket.close()
