More than programming

Markdown is a lightweight, easy to learn markup language for formatting plain text. Its syntax has a one-to-one correspondance with HTML tags, so some prior knowledge here would be helpful but is definitely not a prerequisite. Remember that this article was written in a Jupyter notebook, so all of the narrative text and images you have seen so far was achieved in Markdown. Let’s cover the basics with a quick example.

Literate programming

这个中心点是 notebook server. 你通过浏览器来连接notebook这个渲染好的网页应用. 你写的代码通过server传给kernel。 kernel执行代码再通过server传给浏览器。当你保存文件为.ipynb后缀的JSON 文本 。

这种架构最好的特点是kernel可以不是基于特定于Python的，你可以运行任何语言。 例如你也可以运行R和 Julia 。所以jupyter不再叫Ipython Notebook。 Jupyter 是 Julia, Python, 和 R的组合. 如果你感兴趣，你可以浏览这个 支持的kernel列表.

另外一个好处是你可以通过网络在任何一个地方访问Server。特别的是，你可以在自己的电脑上访问数据存储的地方并运行代码。 你可以在一个远程服务器上执行代码 。
