Python 为什么我在打印图像时会出错

我试图在我正在做的游戏中加入一个敌人。但是当我运行这个项目时，python报告了一个“TypeError”

File "C:\Users\Zee_S\OneDrive\Desktop\python projects\lil Shooter\Player\Lil Shooter.py", line 153, in draw
    screen.blit(ZwalkRight[self.walkcount//3] (self.x, self.y))
TypeError: 'pygame.Surface' object is not callable
[Finished in 1.4s]

但是我看了我的代码，它看起来很好

class Enemy(object):

    ZwalkRight = [pygame.image.load('ZR1.png'), pygame.image.load('ZR2.png'),]
    ZwalkLeft = [pygame.image.load('ZL1.png'), pygame.image.load('ZL2.png'),]
        
    def __init__(self, x, y, width, height, end):
        self.x = x
        self.y = y
        self.width = width
        self.height = height
        self.end = end
        self.path = [self.x, self.end]
        self.walkcount = 0
        self.velo = 3

    def draw(self,win):
        self.move()
        if self.walkcount + 1 <= 33:
            self.walkcount = 0

        if self.velo > 0:
            screen.blit(self.ZwalkRight[self.walkcount//3] (self.x, self.y))
            walkcount += 1
        else:
            win.blit(self.ZwalkLeft[self.walkcount //3] (self.x, self.y))
            walkcount += 1
    def move(self):
        if self.velo > 0:
            if self.x +  self.velo < self.path[1]:
                self.x += self.velo
            else:
                self.velo = self.velo * -1
                self.walkcount = 0
        else:
            if self.x - self.vel > self.path[0]:
                self.x += self.velo
            else:
                self.velo = self.velo * -1
                self.walkcount = 0

是否有人可以修复或解释我为什么会出现此错误

在调用

blit

时，在结束方括号后缺少一个逗号：

screen.blit（self.ZwalkRight[self.walkcount//3]（self.x，self.y））

screen.blit（self.ZwalkRight[self.walkcount//3]，（self.x，self.y））

调用blitscreen时，在结束方括号后缺少一个逗号。名称是我对窗口的引用方式确定它工作正常，但行走动画将消失range@Zina：接受Rabbid76的答案，并为新问题创建一个新问题。我将逗号放回，但僵尸行走的动画显然是超出范围

def redrawGameWindow():
    screen.blit(bg, (0,-100))
    man.draw(screen)
    zombie.draw(screen)
    for bullet in bullets:
        bullet.draw(screen)
    pygame.display.update()

    
    pygame.display.update()

man = Player(300, 508, 64, 64)
zombie = Enemy(100, 508, 64, 64, 450)
bullets = []
run = True
while run:
     [...]
