1、Popen.pid 获取子进程的进程ID。 2、Popen.returncode 获取进程的返回码。如果进程未结束,将返回None。 3、communicate(input=None) 官方解释: AI检测代码解析 Interact with process: Send data to stdin. Read data from stdout and stderr, until end-of-file is reached. Wait for ...
os.popen(cmd, mode='r', buffering=-1) Open a pipe to or from command cmd. The return value is an open file object connected to the pipe, which can be read or written depending on whether mode is 'r' (default) or 'w'. The buffering argument has the same meaning as the correspond...
process= subprocess.Popen("command", stdout=subprocess.PIPE, shell=True)forlineinprocess.stdout: print(line.decode().strip()) subprocess.Popen()函数创建一个子进程来执行指定的命令,并将输出管道连接到主进程。我们可以通过迭代process.stdout来逐行获取输出。
