subprocess.connected

• 类型：<boolean> 在调用 subprocess.disconnect() 后设置为 false。

subprocess.connected 属性表示是否仍然可以与子进程发送和接收消息。当 subprocess.connected 为 false 时，已无法再发送或接收消息。

【The subprocess.connected property indicates whether it is still possible to send and receive messages from a child process. When subprocess.connected is false, it is no longer possible to send or receive messages.】
