Python在线运行代码助手
作者：廖雪峰 时间：2022-05-04 04:09:21
Python代码运行助手可以让你在线输入Python代码，然后通过本机运行的一个Python脚本来执行代码。原理如下：
在网页输入代码：
点击Run按钮，代码被发送到本机正在运行的Python代码运行助手；
Python代码运行助手将代码保存为临时文件，然后调用Python解释器执行代码；
网页显示代码执行结果：

运行
在存放learning.py的目录下运行命令：
C:\Users\michael\Downloads> python learning.py
如果看到Ready for Python code on port 39093...表示运行成功，不要关闭命令行窗口，最小化放到后台运行即可：
试试效果
需要支持HTML5的浏览器：
