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!

| Import hook extending pytz package with usable, generic timezones: | |

| 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." |

Using Python's built-in defaultdict we can easily define a tree data structure:
def tree(): return defaultdict(tree)That's it!

木犀Web组的目标,是培养全面的工程师,甚至是无所不能的全栈工程师,当然大家离这个目标还很远。 首先在毕业之前,我们要深入一个方面,好好学习,有一技之长。对于web中的其他方面,要有一个感性的认识,也就是有实际的操作。 对于自己的专业方向,要了解原理,这样学其他的技术也会比较轻松。 在以后的工作中,一直学习,保持对新技术的热情和对打造优美软件的追求,未来就是你的。
当然最重要的是要享受这个过程,编程就像魔法一样,这不是很神奇吗?
