Import hook extending pytz package with usable, generic timezones:
GMT-14 up to GMT+12.

Note that pytz already has Etc/GMT+X timezones, but
(quoting Wikipedia):

"In order to conform with the POSIX style, those zones beginning with "Etc/GMT"
have their sign reversed from what most people expect. In this style,
zones west of GMT have a positive sign and those east have a negative sign."

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！

One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!
