Python 如何正确调用类

我是一个Python新手（一般来说也是编程新手），我正在尝试制作一个基于文本的、无休止的rpg，其中包含基于列表的随机房间/遭遇。这段代码（当然）还没有完成，只是为了测试。请注意，我从另一个.py文件导入了敌人：

import Enemies
import random    


class Room:
# template definition to define all rooms
    def __init__(self, intro):
        self.intro = intro


class VsRoom(Room):
# room with an enemy
    def __init__(self, enemy):
        self.enemy = random.choice(Enemy_List)
        super().__init__(intro = "There's an enemy here!")


class NullRoom(Room):
# empty, boring room
    def __init__(self):
        super().__init__(intro = "Nothing Interesting here.")


Rooms = [VsRoom, NullRoom]  # All future room "types" will go here


def print_room():
# Tells the player which kind of room they are
    print("You enter the next room...")
    Gen_Room = random.choice(Rooms)
    print(Gen_Room.intro)

我希望print room（）打印“你进入下一个房间…”，从列表中随机选择一个房间，然后打印它的简介，但当我尝试运行它时，我得到以下结果：

You enter the next room...
[...]
 print(Gen_Room.intro)
AttributeError: type object 'NullRoom' has no attribute 'intro'

Process finished with exit code 1

我正在努力学习如何上课，任何帮助对我都是非常好的。我试着尽可能地遵循PEP8，也试着找到类似的问题，但没有成功。

从我观察到的情况来看，你有一个选择敌人的列表，因此你不需要输入该参数：

class VsRoom(Room):
# room with an enemy
    def __init__(self):
        self.enemy = random.choice(Enemy_List)
        super().__init__(intro = "There's an enemy here!")

要创建实例，必须按以下步骤执行：

{class name}()

所以你必须改变：

Gen_Room = random.choice(Rooms)

致：

完整代码：

import Enemies
import random    

class Room:
# template definition to define all rooms
    def __init__(self, intro):
        self.intro = intro


class VsRoom(Room):
# room with an enemy
    def __init__(self):
        self.enemy = random.choice(Enemy_List)
        super().__init__(intro = "There's an enemy here!")


class NullRoom(Room):
# empty, boring room
    def __init__(self):
        super().__init__(intro = "Nothing Interesting here.")


Rooms = [VsRoom, NullRoom]  # All future room "types" will go here


def print_room():
# Tells the player which kind of room they are
    print("You enter the next room...")
    Gen_Room = random.choice(Rooms)()
    print(Gen_Room.intro)

您在

def\u init\u（self，敌方）中使用敌方时，敌方列表的值是什么？

敌方列表是来自另一个名为
敌方
的.py文件的列表。在
def\u init\u（self，敌人）：
中存在敌人是不必要的，如下所述。谢谢，它现在起作用了。我还忘了键入敌人。敌人列表而不是敌人列表。
import Enemies
import random    

class Room:
# template definition to define all rooms
    def __init__(self, intro):
        self.intro = intro


class VsRoom(Room):
# room with an enemy
    def __init__(self):
        self.enemy = random.choice(Enemy_List)
        super().__init__(intro = "There's an enemy here!")


class NullRoom(Room):
# empty, boring room
    def __init__(self):
        super().__init__(intro = "Nothing Interesting here.")


Rooms = [VsRoom, NullRoom]  # All future room "types" will go here


def print_room():
# Tells the player which kind of room they are
    print("You enter the next room...")
    Gen_Room = random.choice(Rooms)()
    print(Gen_Room.intro)
