Python 如何使用类正确定义对象？

我是Python新手。在来到这里询问之前，我已经搜索了几个小时来了解为什么会发生这种情况。请帮助我了解如何正确使用类/对象。提前感谢您的帮助和耐心

这里是错误

第46行，在

打印（“大脑：”，英雄。大脑）

AttributeError:“超级英雄”对象没有“大脑”属性

#Importing Random Module

import random

#create Superhero class

class Superhero():
    #initializing our class and setting its atrributes
    def _init_(self):
        self.superName = superName
        self.power = power
        self.braun = braun
        self.brains = brains
        self.stamina = stamina
        self.wisdom = wisdom
        self.constitution = constitution
        self.dexterity = dexterity
        self.speed = speed

# adding random values to each

braun = random.randint(1,20)
brains = random.randint(1,20)
stamina = random.randint(1,20)
wisdom = random.randint(1,20)
constitution = random.randint(1,20)
dexterity = random.randint(1,20)
speed = random.randint(1,20)


print("Please enter your Super Hero name: ")

# creating the super hero object
hero = Superhero()

# assigning a value to superName using the user's input
hero.superName = input('>')

# print the result of the created object, including its parameters

print("Your name is %s. " % (hero.superName))
print("Your new stats are: ")
print("")
print("Brains: ", hero.brains)
print("Braun: ", hero.braun)
print("Stamina: ", hero.stamina)
print("Wisdom: ", hero.wisdom)
print("Constitution: ", hero.constitution)
print("Dexterity: ", hero.dexterity)
print("Speed: ", hero.speed)
print("")

你需要告诉超级英雄英雄英雄的属性是什么。在类之外定义它们只会创建与类具有0关系的变量。以下是我的建议：

hero = SuperHero(superName = input("Please enter your Super hero name:"),brains = random.randint(1,20)

然后，您可以打印指定给刚刚创建的对象“英雄”的属性：

print("Your name is {}".format(hero.superName))

可以肯定的是，这是你的全部代码吗？因为这里的问题很简单。您忘记将参数添加到类构造函数中。您为统计数据分配了随机数，但它们超出了对象范围，这意味着您的超级英雄不会访问这些变量，除非您将它们作为参数传递给构造函数

有两种方法可以解决这个问题：

A） 在构造函数中作为参数传递它们，因此

class Superhero():
    #initializing our class and setting its atrributes
    def _init_(self, superName, power, braun, brains, stamina, wisdom, constitution, dexterity, speed):
        self.superName = superName
        self.power = power
        self.braun = braun
        self.brains = brains
        self.stamina = stamina
        self.wisdom = wisdom
        self.constitution = constitution
        self.dexterity = dexterity
        self.speed = speed

print("Please enter your Super Hero name: ")
superName = input('>')

power = random.randint(1,20)
braun = random.randint(1,20)
brains = random.randint(1,20)
stamina = random.randint(1,20)
wisdom = random.randint(1,20)
constitution = random.randint(1,20)
dexterity = random.randint(1,20)
speed = random.randint(1,20)

hero = Superhero(superName, power, braun, brains, stamina, wisdom, constitution, dexterity, speed)

然后你可以打印你想要的任何东西

B） 由于您的统计数据都是随机的，您可以告诉构造函数将它们分配给随机数，这会将代码缩短几行，但在创建对象时不允许您分配自己的统计数据，如下所示：

class Superhero():
    #initializing our class and setting its atrributes
    def _init_(self, superName):
        self.superName = superName
        self.power = random.randint(1,20)
        self.braun = random.randint(1,20)
        self.brains = random.randint(1,20)
        self.stamina = random.randint(1,20)
        self.wisdom = random.randint(1,20)
        self.constitution = random.randint(1,20)
        self.dexterity = random.randint(1,20)
        self.speed = random.randint(1,20)

print("Please enter your Super Hero name: ")
superName = input('>')

hero = Superhero(superName)

你所有的变量

braun

，

大脑

，

耐力

等都需要在类内。因为Python不使用括号，所以需要匹配缩进。此外，考虑设置类构造函数将这些变量作为参数（即<代码>（布劳恩，Sug，……）/代码>），它应该是<代码> DEFSy-ITITYI（SUBLY）：< /代码>。两端各有两个下划线。谢谢雅各布·K和贾斯汀·以西奎尔，真的很感谢谢谢你Pjones 98，感谢你花时间帮忙很高兴我能帮忙！谢谢你Saulo Leão，感谢你花时间回复。将会有更多的代码，但目前就是这样。我一直在测试，以确保我在正确的轨道上。
