如何发送/接收多个数据？python套接字？

import socket

# 创建套接字
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 连接到服务器
server_address = ('localhost', 8888)
sock.connect(server_address)

# 要发送的数据列表
data_list = ['data1', 'data2', 'data3']

# 发送数据
for data in data_list:
    sock.sendall(data.encode())

# 关闭套接字
sock.close()

import socket

# 创建套接字
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 绑定地址和端口
server_address = ('localhost', 8888)
sock.bind(server_address)

# 监听连接
sock.listen(1)

# 等待客户端连接
print('等待连接...')
connection, client_address = sock.accept()
print('连接已建立:', client_address)

# 接收数据
data_list = []
while True:
    data = connection.recv(1024)
    if not data:
        break
    data_list.append(data.decode())

# 打印接收到的数据
print('接收到的数据:', data_list)

# 关闭连接
connection.close()
sock.close()
