第 1 章：准备工作 在通过这本书学习 Flask 开发前，我假设你了解了 Python 和 HTML 的基础知识。 你的 Python 版本可以是 2.7，也可以是 3.3 及以上版本。电脑的操作系统可以是 Windows，也可以是 macOS 或 Linux。 安装编辑器和浏览器 对于编辑器来说，每个人都有不同的偏好，你可以自由选择。可以选择功能丰富的 IDE（集成开发环境），比如 PyCharm；也可以选择相对轻量的编辑器，比如 Atom 或 Sublime Text。浏览器建议使用 Firefox 或 Chrome。 使用命令行 在本书中，你需要使用命令行窗口来执行许多操作。你可以使用 Windows 下的 cmd.exe，或是 macOS 和 Linux 下的终端（Terminal）。下面我们执行一个最简单 的 whoami 命令（即 Who Am I？）： 这个命令会打印出当前计算机用户的名称。其他常用的命令还有 cd 命令，用来 切换目录（change directory）； mkdir 命令，用来创建目录（make directory）。在不同的操作系统上，执行某个操作的命令可能会有所不同，在必要 的地方，书里会进行提示。 我们先来为我们的程序创建一个文件夹： $ mkdir watchlist $ cd watchlist 除非特别说明，从现
