我是 Python 新手，我需要一些幫助來理解私有方法。我正在做一項(xiàng)任務(wù)，我必須輸出寵物的類型、名稱和年齡。我的程序正在運(yùn)行，但我似乎被困在如何將數(shù)據(jù)屬性設(shè)為私有的問題上。這是我的代碼。import random       class pet :#how the pets attributes will be displayeddef __init__(animal, type, name, age):     animal.type = type                animal.name = name    animal.age = age    #empty list for adding tricks    animal.tricks = []#number of fleas are random from 0 to 10fleaCount = random.randint(0,10)    def addTrick(animal, trick):    animal.tricks.append(trick)       def petAge(animal):    return animal.age         def printInfo(animal):            print(f"Pet type : {animal.type} \nPet name : {animal.name}\nPet age : {animal.age}\nPet                            fleas : {animal.fleaCount}")    print("Tricks :")          for i in range(len(animal.tricks)):        print("",animal.tricks[i])# main program#dog1 informationdog1 = pet("Dog","Max",10)        dog1.addTrick("Stay and Bark")              dog1.printInfo()                #dog2 informationdog2 = pet("Dog","Lily",8)dog2.addTrick("Play Dead and Fetch")dog2.printInfo()#cat1 informationcat1 = pet("Cat","Mittens",11)cat1.addTrick("Sit and High Five")cat1.printInfo()
