stdin, stdout和stderr也可以是已经打开的 file 对象,前提是以合理方式打开,比如stdin对应的文件必须要可读等。 父进程如果想要和子进程通过communicate() 方法通信,对应的参数必须是subprocess.PIPE(见下文例4); preexec_fn:默认是None,否则必须是一个函数或者可调用对象,在子进程中首先执行这个函数,然后再去执行为...
subprocess.check_call(*popenargs, *kwargs):与subprocess.call(popenargs, **kwargs)功能一样,只是如果子进程返回的returncode不为0的话,将触发CalledProcessError异常。在异常对象中,包括进程的returncode信息。 程序中运行其他程序 可以这样写 subprocess.Popen('脚本/shell', shell=True) 也可以这样 subprocess.c...

Since the discovery of neutrino oscillations, we know that neutrinos have non-zero mass. However, the absolute neutrino-mass scale remains unknown. Here we report the upper limits on effective electron anti-neutrino mass, mν, from the second physics run
