一、作业内容：习题42-45
二、模块、类、对象三种概念一定要弄清楚。模块（module）与字典相似,模组是包含函数和变量的.py文件，可以调用（import）这个文件,然后使用
‘.’操作符访问到模组中的函数和变量

--------
The Gothons of Planet Percel # 25have invaded your ship and destroyed
your entire crew. You are the last surviving member and your last
mission is to get the neutron destruct bomb from the Weapons Armory,
put it in the bridge, and blow the ship up after getting into an
escape pod.
You're running down the central corridor to the Weapon Armory when
a Gothon jumps out, red scaly skin, dark grimy teeth, and evil clown costume
flowing around his hate filled body. He's blocking the door to the
Armory and about to pull a weapon to blast you.

>tell a joke
Lucky for you they made you learn Gothon insults in the academy.
You tell the one Gothon joke you know:
Lbhe zbgure vf fb sng, jura fur fvgf nebhaq gur ubhfr, fur fvgf nebhaq gur ubhfr.
The Gothon stops, tries not to laugh, then busts out laughing and can't move.
While he's laughing you run up and shoot him square in the head

You do a dive roll into the Weapon Armory, crouch and scan the room
for more Gothons that might be hiding. It's dead quiet, too quiet.
You stand up and run to the far side of the room and find the
neutron bomb in its container. There's a keypad lock on the box
and you need the code to get the bomb out. If you get the code
wrong 10 times then the lock closes forever and you can't
get the bomb. The code is 3 digits.

The lock buzzes one last time and then you hear a sickening
melting sound as the mechanism is fused together.
You decide to sit there, and finally the Gothons blow up the
ship from their ship and you die.

Nice job, you died ... jackass.

注意：模块，相当于一种特殊字典的作用，通过这种方式存储python代码，通过‘.’操作符访问到这些代码；类，相当于把一组函数和数据放到一个容器中，从而用‘.’操作符访问到它们。类的好处在于可重复创建出好多来，它们也不会相互干涉，而模块当你import之后，整个程序里就只有这一份内容。其中类要实例（instance）化，就是创建的意思，当创建后便可以得到一个对象（object）.
