我使用不同的类在我使用pygame制作的游戏中创建我的角色。正如您所看到的，这些类几乎是相同的，唯一的区别是 self.walkRight 及 self.walkLeft . 所以我想知道一种方法，我可以复制第一个类，只修改我想更改的内容。我该怎么做？守则：

class enemy(object):
    def __init__(self, x, y, width, height, end):
        self.walkRight = [pygame.image.load('resources/R1ENEMY.png'), pygame.image.load('resources/R2ENEMY.png'),
                          pygame.image.load('resources/R3ENEMY.png'),
                          pygame.image.load('resources/R4ENEMY.png'), pygame.image.load('resources/R5ENEMY.png'),
                          pygame.image.load('resources/R6ENEMY.png'),
                          pygame.image.load('resources/R7ENEMY.png'), pygame.image.load('resources/R8ENEMY.png'),
                          pygame.image.load('resources/R9ENEMY.png'),
                          pygame.image.load('resources/R10ENEMY.png'), pygame.image.load('resources/R11ENEMY.png')]
        self.walkLeft = [pygame.image.load('resources/L1ENEMY.png'), pygame.image.load('resources/L2ENEMY.png'),
                         pygame.image.load('resources/L3ENEMY.png'),
                         pygame.image.load('resources/L4ENEMY.png'), pygame.image.load('resources/L5ENEMY.png'),
                         pygame.image.load('resources/L6ENEMY.png'),
                         pygame.image.load('resources/L7ENEMY.png'), pygame.image.load('resources/L8ENEMY.png'),

        self.health = 10
        self.visible = True
        self.spawn = [self.x, self.y, self.width, self.height, self.end]

    def draw(self, win):
        self.move()

使用类继承可以访问父类的所有方法，也可以添加自己的方法。
下面是类继承的一个示例。注意父类（fivenumbers）如何访问自己的方法。子类（tennumbers）可以与其父类的方法一起访问自己的方法。

class FiveNumbers:
    def __init__(self):
        self.one = 1
        self.two = 2
        self.three = 3
        self.four = 4
        self.five = 5

class TenNumbers(FiveNumbers):
    def __init__(self):
        super().__init__()
        self.six = 6
        self.seven = 7
        self.eight = 8
        self.nine = 9
        self.ten = 10

# Is the parent class able to access the methods of the parent class?

test_1 = FiveNumbers()
print(test_1.one)
print(test_1.two)

# Is the child class able to access the methods of the parent and child class?

test_2 = TenNumbers()
print(test_2.one)
print(test_2.two)
print(test_2.six)
print(test_2.ten)

# Is the parent class able to access methods of the child class?

print(test_1.six)  # This will give an error
print(test_1.ten)  # This will give an error (assuming you fixed the previous line)

简单的继承

class boss(enemy):

    def __init__(self, x, y, width, height, end):
        self.walkRight = [pygame.image.load('resources/BOSSR1.png'), pygame.image.load('resources/BOSSR2.png'),
            pygame.image.load('resources/BOSSR3.png'),
            pygame.image.load('resources/BOSSR4.png'), pygame.image.load('resources/BOSSR5.png'),
            pygame.image.load('resources/BOSSR6.png'),
            pygame.image.load('resources/BOSSR7.png'), pygame.image.load('resources/BOSSR8.png'),
            pygame.image.load('resources/BOSSR9.png'),
            pygame.image.load('resources/BOSSR10.png'), pygame.image.load('resources/BOSSR11.png')]
        self.walkLeft = [pygame.image.load('resources/BOSSL1.png'), pygame.image.load('resources/BOSSL2.png'),
            pygame.image.load('resources/BOSSL3.png'),
            pygame.image.load('resources/BOSSL4.png'), pygame.image.load('resources/BOSSL5.png'),
            pygame.image.load('resources/BOSSL6.png'),
            pygame.image.load('resources/BOSSL7.png'), pygame.image.load('resources/BOSSL8.png'),
            pygame.image.load('resources/BOSSL9.png'),
            pygame.image.load('resources/BOSSL10.png'), pygame.image.load('resources/BOSSL11.png')]
    super().__init__(elf, x, y, width, height, end)
