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++。

#!/usr/bin/envpython3
#-*-coding:utf-8-*-

ifv.major==3andv.minor>=4:
returnTrue
print('Yourcurrentpythonis%d.%d.PleaseusePython3.4.'%(v.major,v.minor))
returnFalse

ifnotcheck_version():
exit(1)

2、再用一个记事本写如下的代码：
