Python代码运行助手是一种可以在网页上运行Python语言的工具。由于Python的运行环境在许多教程中都是使用DOS的，界面显得有些简陋，因此出现了这种代码运行助手，作为IDE使用。
python代码运行助手是能在网页上运行python语言的工具。因为python的运行环境在很多教程里都是用dos的，黑乎乎的界面看的有点简陋，所以出了这python代码运行助手，作为ide。
实际上，python代码运行助手界面只能算及格分，如果要找ide，推荐使用jupyter。jupyter被集成到ANACONDA里，只要安装了anacoda就能使用了。
1、要打开这运行助手首先要下载一个learning.py，如果找不到可以复制如下代码另存为“learning.py”,编辑器用sublime、或者notepad++。
