Python程序使用类程序模拟掷两个骰子

Question

我的程序应该模拟单个骰子的角色和两个骰子的角色，但我遇到了问题。这是我的代码的样子：

import random

#Dice class simulates both a single and two dice being rolled
#sideup data attribute with 'one'

class Dice:
    #sideup data attribute with 'one'

    def __init__(self):
        self.sideup='one'
    def __init__(self):
        self.twosides='one and two'

 #the toss method generates a random number
 #in the range of 1 through 6.


    def toss(self):
        if random.randint(1,6)==1:
            self.sideup='one'
        elif random.randint(1,6)==2:
            self.sideup='two'
        elif random.randint(1,6)==3:
            self.sideup='three'
        elif random.randint(1,6)==4:
            self.sideup='four'
        elif random.randint(1,6)==5:
            self.sideup='five'
        else:
            self.sideup='six'
    def get_sideup(self):
        return self.sideup
    def doubletoss(self):
        if random.randint(1,6)==1 and random.randint(1,6)==2:
            self.twosides='one and two'
        elif random.randint(1,6)==1 and random.randint(1,6)==3:
            self.twosides='one and three'
        elif random.randint(1,6)==1 and random.randint(1,6)==4:
            self.twosides='one and four'
        elif random.randint(1,6)==1 and random.randint(1,6)==5:
            self.twosides='one and five'
        elif random.randint(1,6)==1 and random.randint(1,6)==6:
            self.twosides='one and six'
        elif random.randint(1,6)==1 and random.randint(1,6)==1:
            self.twosides='one and one'
    def get_twosides(self):
        return self.twosides






#main function
def main():
    #create an object from the Dice class
    my_dice=Dice()


    #Display the siide of the dice is factory
   print('This side is up',my_dice.get_sideup())

    #toss the dice
    print('I am tossing the dice')
    my_dice.toss()

    #toss two dice
    print('I am tossing two die')
    my_dice.doubletoss()

   #Display the side of the dice that is facing up
    print('this side is up:',my_dice.get_sideup())

    #display both dices with the sides of the dice up
    print('the sides of the two dice face up are:',my_dice.get_twosides())



main()

这是我运行程序时的输出：

"Traceback（最近一次调用最后一次）： 文件“C:/Users/Pentazoid/Desktop/PythonPrograms/DiceClass.py”，第 79 行，在 主要的（） 文件“C:/Users/Pentazoid/Desktop/PythonPrograms/DiceClass.py”，第 61 行，在 main print('这面朝上',my_dice.get_sideup()) 文件“C:/Users/Pentazoid/Desktop/PythonPrograms/DiceClass.py”，第 32 行，在 get_sideup 返回self.sideup

AttributeError: 'Dice' 对象没有属性 'sideup'

我做错了什么？

Answer 1

您有两个 init 方法。第二个取代了第一个，否定了你对 sideup 的定义。

改为：

def __init__(self):
    self.sideup='one'
    self.twosides='one and two'
