編譯代碼時出現屬性錯誤

Question

我當時正在製作一個小動物看護程序，其中我首先創建了一個類名Critter。 我創建的第一個方法是構造函數方法，其中我做了三個名爲「名稱」，「飢餓」，「無聊」的變量。
我在這堂課創建了很多方法。

我無法弄清楚我做錯了什麼。

def Critter(object): 

    def init(self,name,hunger = 0,boredom = 0): 
     self.name = name 
     self.hunger = hunger 
     self.boredom = boredom 

    def increase(self): 
     self.hunger += 2 
     self.boredom += 2 
     return hunger,boredom 

    def mood(self): 
     unhappiness = self.hunger + self.boredom 
     if 5 < unhappiness < 9: 
      mood1 = "unhappy." 
     elif 9 < unhappiness < 14: 
      mood1 = "Frustrated" 
     elif unhappiness > 14: 
      mood1 = "Mad" 
     return mood1 

    def talk(self): 
     print "Critter's name is ",self.name.upper()," and it is ",self.mood()," today." 

    def eat(self,food = 4): 
     self.hunger -= food 
     if self.hunger < 0: 
      self.hunger = 0 
     self.increase() 

    def play(self,play = 4): 
     self.boredom -= play 
     if self.boredom < 0: 
      self.boredom = 0 
     self.increase() 

def main(): 
    choice = None 
    name = raw_input("Please enter the name of the critter = ") 
    crit1 = Critter(name) 
    while choice != 0: 

     print """ 

     0 - EXIT 
     1 - SEE YOUR CRITTER'S MOOD 
     2 - FEED YOUR CRITTER 
     3 - PLAY WITH YOUR CRITTER 

     """ 
     choice = int(raw_input("Enter your choice = ")) 
     if choice == 1: 
      crit1.talk() 

     elif choice == 2: 
      crit1.eat() 

     elif choice == 3: 
      crit1.play() 

    if choice == 0: 
     print "Good bye ......" 

main() 


THIS IS THE CODE ,when i run it shows an error 

Traceback (most recent call last): 
    File "C:\Users\sahib navlani\Desktop\gfh.py", line 65, in <module> 
    main() 
    File "C:\Users\sahib navlani\Desktop\gfh.py", line 54, in main 
    crit1.talk() 
AttributeError: 'NoneType' object has no attribute 'talk' 

Answer 1

您至少有兩個問題。

一個是你需要使用

class Critter(object): 

不

def Critter(object): 

第二是

def init(self, name, hunger=0, boredom=0): 

應該

def __init__(self, name, hunger=0, boredom=0):
