這篇文章將為大家詳細(xì)講解有關(guān)python代碼助手指的是什么,小編覺得挺實(shí)用的,因此分享給大家做個參考,希望大家閱讀完這篇文章后可以有所收獲。
我們注重客戶提出的每個要求,我們充分考慮每一個細(xì)節(jié),我們積極的做好成都網(wǎng)站設(shè)計(jì)、成都網(wǎng)站制作服務(wù),我們努力開拓更好的視野,通過不懈的努力,成都創(chuàng)新互聯(lián)贏得了業(yè)內(nèi)的良好聲譽(yù),這一切,也不斷的激勵著我們更好的服務(wù)客戶。 主要業(yè)務(wù):網(wǎng)站建設(shè),網(wǎng)站制作,網(wǎng)站設(shè)計(jì),成都小程序開發(fā),網(wǎng)站開發(fā),技術(shù)開發(fā)實(shí)力,DIV+CSS,PHP及ASP,ASP.Net,SQL數(shù)據(jù)庫的技術(shù)開發(fā)工程師。
python代碼運(yùn)行助手是能在網(wǎng)頁上運(yùn)行python語言的工具。因?yàn)閜ython的運(yùn)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(diǎn)簡陋,所以出了這python代碼運(yùn)行助手,作為ide。
實(shí)際上,python代碼運(yùn)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。
要打開這運(yùn)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++。

再用一個記事本寫如下的代碼:
@echo off python learning.py pause
另存為‘運(yùn)行.bat’
把“運(yùn)行.bat”和“l(fā)earning.py”放到同一目錄下
雙擊運(yùn)行“運(yùn)行.bat",之后會彈出黑色的dos窗口,這個窗口不要關(guān)閉。
輸入網(wǎng)址對應(yīng)的網(wǎng)址和端口,整個過程就完成了。
關(guān)于python代碼助手指的是什么就分享到這里了,希望以上內(nèi)容可以對大家有一定的幫助,可以學(xué)到更多知識。如果覺得文章不錯,可以把它分享出去讓更多的人看到。
