python如何使用程式碼執行助手

阿新 • • 發佈：2020-07-03

python程式碼執行助手是能在網頁上執行python語言的工具。因為python的執行環境在很多教程裡都是用dos的，黑乎乎的介面看的有點簡陋，所以出了這python程式碼執行助手，作為ide。

實際上，python程式碼執行助手介面只能算及格分，如果要找ide，推薦使用jupyter。jupyter被整合到ANACONDA裡，只要安裝了anacoda就能使用了。

1、要開啟這執行助手首先要下載一個learning.py，如果找不到可以複製如下程式碼另存為“learning.py”,編輯器用sublime、或者notepad++。

returnFalse

exceptsubprocess.CalledProcessErrorase:
r=dict(error='Error',output='執行錯誤')
print('Executedone.')
return[json.dumps(r).encode('utf-8')]

if__name__=='__main__':
main()

2、再用一個記事本寫如下的程式碼：

@echooff
pythonlearning.py
pause

另存為‘執行.bat'

3、把“執行.bat”和“learning.py”放到同一目錄下。

4、雙擊執行“執行.bat"，之後會彈出黑色的dos視窗，這個視窗不要關閉。

5、輸入網址對應的網址和埠，整個過程就完成了。
