python代码运行助手怎么打开
8个回答
展开全部
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。
回到这个问题：
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/env python3

r = dict(error='Error', output='执行错误')
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。

python代码运行助手怎么打开：
Python代码运行助手可以在线输入Python代码，通过本机运行的一个Python脚本来执行代码。
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。（需要支持HTML5的浏览器）

Python代码运行助手有很多种工具和方式可以打开，具体取决于你选择的工具和平台。以下介绍几种常见的方法：1. 使用Python集成开发环境（IDE）：例如PyCharm、Visual Studio Code、Spyder等，打开IDE后，新建项目或者文件，将代码复制进去，点击运行即可。2. 使用命令行工具：在Windows系统中，可以打开CMD或PowerShell，输入python代码，按回车键即可运行代码。在Mac或Linux系统中，可以打开终端，输入python代码，按回车键即可运行代码。3. 使用在线平台：例如Jupyter Notebook等，打开网页，新建Notebook，将代码复制进去，点击运行即可。

是廖雪峰的python教程吧，下载learning.py，在cmd里运行，然后在教程的页面里面就可以用了。目的是网页里就可以测试代码。
