如何在客户端-socket服务器交互中停止循环

import socket

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

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

# 标志变量
isRunning = True

while isRunning:
    # 接收服务器发送的数据
    data = client_socket.recv(1024)
    # 处理接收到的数据
    # ...

    # 检查是否需要停止循环
    if data == b'stop':
        isRunning = False

# 关闭socket连接
client_socket.close()

import socket

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

# 绑定服务器地址和端口
server_address = ('localhost', 8888)
server_socket.bind(server_address)

# 监听连接
server_socket.listen(1)

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

# 向客户端发送数据
client_socket.sendall(b'Hello, client!')

# 根据条件发送停止循环的信号
if condition:
    client_socket.sendall(b'stop')

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