subprocess.CalledProcessError: Command 'exit 1' returned non-zero exit status 1 注意:针对该函数,不要使用stdout=PIPE 或 stderr=PIPE。因为不是从当前进程中读取管道(pipe),如果子进程没有生成足够的输出来填充OS的管道缓冲区,可能会阻塞子进程。 subprocess.check_output(args, *, stdin=None, stderr=None...
The new process has a new console, instead of inheriting its parent’s console (the default). This flag is always set when Popen is created with shell=True. subprocess.CREATE_NEW_PROCESS_GROUP A Popen creationflags parameter to specify that a new process group will be created. This flag is...
Wait for child process to terminate. Returns returncode attribute.(等待子进程执行结束,并返回returncode属性,如果为0表示执行成功。) 1. 6、send_signal( sig) Send a signal to the process(发送信号给子进程。) 1. 7、terminate() Terminates the process(终止子进程。windows下将调用Windows API TerminateP...
asyncio.subprocess.Process 类提供了由 asyncio 运行的子进程的表示。它在 asyncio 程序中提供子进程的句柄,允许对其执行操作,例如等待和终止它。 该API与 multiprocessing.Process 类非常相似,可能与 subprocess.Popen 类更相似。具体来说,它与 subprocess.Popen 共享 wait()、communicate() 和 send_signal() 等方法...

4、Popen.send_signal(signal) 向子过程发送信号(在Posix os上)。 5、Popen.terminate() 停止子过程。实际上是向子过程发送SIGTERM信号(在Posix os上)。 6、Popen.kill() 杀掉子过程。实际上是向子过程发送SIGKILL信号(在Posix os上)。 7、Popen.args ...
print("parent process") 此外,你还可以在父进程中对子进程进行其它操作,比如我们上面例子中的child对象: child.poll() # 检查子进程状态 child.kill() # 终止子进程 child.send_signal() # 向子进程发送信号 child.terminate() # 终止子进程 子进程的PID存储在child.pid。
在UDP服务器端,我们不需要调用listen()和accept(),而是直接recvfrom()和sendto(): server_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) server_socket.bind(('localhost', 9000)) while True: data, address = server_socket.recvfrom(1024) message = data.decode('utf-8') print(f"Recei...
