python如何使用代码运行助手

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++。

    print(\'Execute done.\')
    return [json.dumps(r).encode(\'utf-8\')]
 
if __name__ == \'__main__\':
    main()

2、再用一个记事本写如下的代码：

@echo off
python learning.py
pause

另存为‘运行.bat\’

3、把“运行.bat”和“learning.py”放到同一目录下。

4、双击运行“运行.bat\”，之后会弹出黑色的dos窗口，这个窗口不要关闭。

5、输入网址对应的网址和端口，整个过程就完成了。
