This blocking function will start a process and wait until the new process exits before moving on. The documentation recommends using run() for all cases that it can handle. For edge cases where you need more control, the Popen class can be used. Popen is the underlying class for the ...

父进程启动一个新的python解释器进程。子进程将只继承那些运行进程对象run()方法所需的资源。特别是,来自父进程的不必要的文件描述符和句柄将不会被继承。与使用fork或forkserver相比,使用此方法启动进程相当慢。可在Unix和Windows上使用。Windows上默认使用该启动方法。
