Django 中提供了开发网站经常用到的模块，常见的代码都为你写好了，通过减少重复的代码，Django 使你能够专注于 web 应用上有 趣的关键性的东西。为了达到这个目标，Django 提供了通用Web开发模式的高度抽象，提供了频繁进行的编程作业的快速解决方法，以及为“如何解决问题”提供了清晰明了的约定。Django的理念是DRY(Don't Repeat Yourself)来鼓励快速开发！

小贴士
感谢您为本站写下的评论，您的评论对其它用户来说具有重要的参考价值，所以请认真填写。
- 类似“顶”、“沙发”之类没有营养的文字，对勤劳贡献的楼主来说是令人沮丧的反馈信息。
- 相信您也不想看到一排文字/表情墙，所以请不要反馈意义不大的重复字符，也请尽量不要纯表情的回复。
- 提问之前请再仔细看一遍楼主的说明，或许是您遗漏了。
- 请勿到处挖坑绊人、招贴广告。既占空间让人厌烦，又没人会搭理，于人于己都无利。
