// 2fa provides a simple end-to-end example of server side support for google authenticator.
// It sets up a secret for a single user, generates a QR code as a PNG file that the user
// can scan into Google Authenticator, and then prompts the user for a token that the user
// copies from the Authenticator app. We validate the token and print out whether it is valid or not.

一行 Python 实现树

使用 Python 内置的 defaultdict，我们可以很容易的定义一个树形数据结构：

def tree(): return defaultdict(tree)

就是这样！
