python代碼運行助手是能在網(wǎng)頁上運行python語言的工具。因為python的運行環(huán)境在很多教程里都是用dos的，黑乎乎的界面看的有點簡陋，所以出了這python代碼運行助手，作為ide。
成都創(chuàng)新互聯(lián)專業(yè)為企業(yè)提供府谷網(wǎng)站建設(shè)、府谷做網(wǎng)站、府谷網(wǎng)站設(shè)計、府谷網(wǎng)站制作等企業(yè)網(wǎng)站建設(shè)、網(wǎng)頁設(shè)計與制作、府谷企業(yè)網(wǎng)站模板建站服務(wù)，10多年府谷做網(wǎng)站經(jīng)驗，不只是建網(wǎng)站，更提供有價值的思路和整體網(wǎng)絡(luò)服務(wù)。
實際上，python代碼運行助手界面只能算及格分，如果要找ide，推薦使用jupyter。jupyter被集成到ANACONDA里，只要安裝了anacoda就能使用了。
1、要打開這運行助手首先要下載一個learning.py，如果找不到可以復(fù)制如下代碼另存為“l(fā)earning.py”,編輯器用sublime、或者notepad++。
#!/usr/bin/env python3
# -*- coding: utf-8 -*-

learning.py
A Python 3 tutorial from http://www.liaoxuefeng.com
Usage:
python3 learning.py

v = sys.version_info
if v.major == 3 and v.minor >= 4:
return True
print('Your current python is %d.%d. Please use Python 3.4.' % (v.major, v.minor))
return False
if not check_version():
exit(1)

if __name__ == '__main__':
main()
2、再用一個記事本寫如下的代碼：
@echo off python learning.py pause
另存為‘運行.bat’
3、把“運行.bat”和“l(fā)earning.py”放到同一目錄下。
4、雙擊運行“運行.bat"，之后會彈出黑色的dos窗口，這個窗口不要關(guān)閉。
5、輸入網(wǎng)址對應(yīng)的網(wǎng)址和端口，整個過程就完成了。
