笨办法学python3 的习题43 调制版（解析版）
作者：互联网
这个习题我搞了好久，模块这类感觉也挺难的，感觉还有好多没懂，看了好多好多回习题41、42。这道习题里面函数有很多调用，需要很多次打印，所以我就把注释，还有我的解题过程都放出来了。
from random import randint
from sys import exit
from textwrap import dedent
class Scene(object):
print("______7_____class-Scene_____7_____\n")#因为没有调用函数就直接到下一个 Class了
def enter(self):
print(">>>>>>>>暂时不知道这里的是什么<<<<<<<<<<")
print("This scene is not yet configured.")
print("Subclass it and implement enter().")
exit(1)
class Engine(object):
print("_______16_____classEngine______16_____\n")
def __init__(self, scene_map): # class Engine has-a __init__ that takes self and scene_map parameters
self.scene_map = scene_map # Engine has-a attribute named scene_map
print("_______19______ __init__ _______19______",scene_map)
def play(self):
print("_______22______play_______22_____")
current_scene = self.scene_map.opening_scene()#在这里直接调用了 168的函数，所以就跳转到了167
print("\n play of current_scene====24 24======" ,current_scene)#现在这里是CentralCorridor，由165 返还上来的
last_scene = self.scene_map.next_scene('finished')
print("last_scene======26 26=====" ,last_scene)#现在又将 第二次val的函数意义给return返回了这里，由165
while current_scene != last_scene:
print("\n^^^^^^ top of while current_scene==29====29== top ==", current_scene, "last_scene ======== top =======",
last_scene, )
next_scene_name = current_scene.enter()#相当于 CentralCorridor.enter(),所以就开始去到了函数 CentralCorridor. 之后再该函数里面return的 地点名就是小写的地点名，并且是等于next——next_scene_name的
print("next_scene_name == 32 ===== 32 ==",next_scene_name) #31行的函数结束之后就return 给了curren_scene一个新的值，并且从31继续进行下去
current_scene = self.scene_map.next_scene(next_scene_name)#又一次165行return val了一个新的值 LaserWeaponArmory 给了curren_scene一个新的值。 即return的值是等于current_scene
print("\n....... end of while current_scene === 34 === 34 === " ,current_scene, "last_scene======== ",
last_scene,"next_scene_name ==== 35 ==== ", next_scene_name )
# be sure to print out the last scene
