如何讓這個 python 運行程序？

Question

所以這應該在上周四之前完成，我仍在做這個作業，因為它被隔離了，所以我的老師不能真正幫助我完成這項工作，我有點想通了，但它一直給我一個諸如“打印”之類的代碼錯誤位置的錯誤是錯誤的或類似的東西。 我認為這段代碼有問題，我無法弄清楚這段代碼為什么或有什么問題。 請各位大神幫我解釋一下好嗎？

標題不允許我自己制作，所以我必須選擇那個。 不是我的錯： ：）

Answer 1

1. 您在啟動時忘記將所有參數傳遞給 Pet class
2. get__heavier和get__taller使用了不存在的變量

下面是工作拷貝程序

        than second, otherwise returns False.
        is_older: compares two pets' ages. Returns true if self is older
        than second, otherwise returns False.
        Same_colour: compares two pets' colours. Returns True if colours match
        Returns False if Colours don't match.

Answer 2

我認為錯誤是您基於否或論點產生的。 如果你觀察你的代碼

def __init__(self, name, animal_type, age, weight, height):
        self.__name = name
        self.__animal_type = animal_type
        self.__age = age
        self.__heavier = weight
        self.__taller = height

總共需要 5 個參數，而您只傳遞了 3 個參數

pets = Pet(name, animal_type, age)

正確的格式

pets = Pet(name, animal_type, age,weight,height)
