Python属性错误：type对象没有属性 [英] Python Attribute Error: type object has no attribute

问题描述

我很习惯Python和编程（从12月起），并尝试教自己一些面向对象的Python，并在我的lattest项目中得到这个错误：

  AttributeError：type object'Goblin'没有属性'color'
  

我有一个文件来创建怪物类和一个怪物子类，从怪物类扩展。
当我导入这两个类时，控制台不返回错误

 >>从怪物导入Goblin 
>>>> 
  

即使创建一个实例也没有问题：

 >>>> Azog = Goblin 
>>> 
  

但是当我调用我的Goblin类的属性时，控制台返回上面的错误，不明白为什么。
这是完整的代码：

  import random 
 
 COLORS = ['yellow' ，'red'，'blue'，'green'] 
 
 
 class怪物：
 min_hit_points = 1 
 max_hit_points = 1 
 min_experience = 1 
 max_experience = 1 
 weapon ='sword'
 sound ='roar'
 
 def __init __（self，** kwargs）：
 self.hit_points = random.randint（self.min_hitpoints，self.max_hit_points）
 self.experience = random.randint（self.min_experience，self.max_experience）
 self.color = random.choice（COLORS）
 
为key，value in kwargs.items（）：
 setattr（self，key，value）
 
 def warcry（self）：
 return self.sound。 $（$）
 
 
 class Goblin（Monster）：
 max_hit_points = 3 
 max_experience = 2 
 sound ='squiek'
  




解决方案

您不是创建一个实例，而是引用引发类别 Goblin 本身，如错误所示：

AttributeError：类型对象'Goblin'没有属性'color'

将您的行更改为 Azog = Goblin（）

I am new to Python and programming in general (since December) and try to teach myself some Object-Oriented Python and got this error on my lattest project:

AttributeError: type object 'Goblin' has no attribute 'color'

I have a file to create "Monster" classes and a "Goblin" subclass that extends from the Monster class. When I import both classes the console returns no error

>>>from monster import Goblin
>>>

Even creating an instance works without problems:

>>>Azog = Goblin
>>>

But when I call an attribute of my Goblin class then the console returns the error on top and I don't figure out why. Here is the complete code:

import random

COLORS = ['yellow','red','blue','green']


class Monster:
    min_hit_points = 1
    max_hit_points = 1
    min_experience = 1
    max_experience = 1
    weapon = 'sword'
    sound = 'roar'

   def __init__(self, **kwargs):
   self.hit_points = random.randint(self.min_hitpoints, self.max_hit_points)
   self.experience = random.randint(self.min_experience,  self.max_experience)
   self.color = random.choice(COLORS)

       for key,value in kwargs.items():
           setattr(self, key, value)

   def battlecry(self):
   return self.sound.upper()


class Goblin(Monster):
   max_hit_points = 3
   max_experience = 2
   sound = 'squiek'

解决方案

You are not creating an instance, but instead referencing the class Goblin itself as indicated by the error:

AttributeError: type object 'Goblin' has no attribute 'color'

Change your line to Azog = Goblin()
