When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.I'm always learning.

你現在可以從

這個 view function 移除

Bottle
另一個值得嘗試的輕量化框架是Bottle（
http://bottlepy.org/docs/dev/
index.html
）。 Bottle 被實作為單一個
bottle.py
檔案（超過 4,000 行！）。
除了標準程式庫以外，它沒有其他的依存關係（dependencies）。嚴格
來 說，Bottle 不需要安裝：你只需要將它下載到你目前的目錄，例如
透過
curl --location -O http://bottlepy.org/bottle.py
6
，以取得最新
的 development snapshot（不過我們建議你安裝穩定的發行版，使用
pip
install bottle
）。以那單一個
.py
檔案，Bottle 支援了 v2 及 v3。它包括了
一個 web 伺服器，適合用於本地端的開發，甚至還有一個簡單的獨立範本
引擎（template engine，
http://bottlepy.org/docs/dev/stpl.html
）以你的範本中
內嵌的 Python 為基礎（雖然它也能讓你使用 jinja2 或你安裝的其他外部範
本引擎）。
