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  )
