Python 的subprocess.run()函数可以在subprocess模块中找到,它可以在 Python 程序中运行 Shell 命令,然后将命令输出显示为字符串。例如,下面的代码运行ls –al命令: >>>importsubprocess, locale>>>procObj = subprocess.run(['ls','-al'], stdout=subprocess.PIPE)# 1>>>outputStr = procObj.stdout.decode(l...

我们将['ls', '-al']列表传递给subprocess.run()1 。这个列表包含命令名ls,后面是它的参数,作为单独的字符串。注意,通过['ls –al']是不行的。我们将命令的输出作为字符串存储在outputStr2 中。subprocess.run()和locale.getdefaultlocale()的在线文档会让你更好地了解这些函数是如何工作的,但是它们让代码可...
