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...

当运行python/path/to/directory/时,Python 的行为就像我们输入python/path/to/directory/__main__.py一样。 换句话说,Python 会做以下两件事: 将目录/path/to/directory/添加到模块路径中。 执行/path/to/directory/__main__.py中的代码。 运行python /path/to/filename.zip时,Python 会把文件当做一个目录。
