试图比较python中不同类的两个属性，得到错误；TypeError：列表索引必须是整数或切片，而不是Sheep“；

我正在做一个项目，羊在平原上游荡，吃草，而狼在追逐羊。一切都很顺利，直到我找到狼AI，试图将羊的位置与它们自己的位置进行比较。以下是导致错误的代码：

    def trackSheep(self, sheepList):
    sheepFound = 0#0 = false, 1 = true
    for s in sheepList:
        if sheepFound == 0:
            if sheepList[s].x == self.x and sheepList[s].y == self.y:
                self.energy = self.energy + sheepList[s].energy
            else:
                distanceToSheep = sheepList[s].x + sheepList[s].y
                if distanceToSheep < SHEEP_DETECTED_RANGE:
                    return [(sheepList[s].x,  sheepList[s].y)]
                    sheepFound = 1
        else:
            break
    if sheepFound == 0:
        return False

这是由我的主要功能触发的：

    def update(self, sheepList):#all logic for the wolves
    if self.isAlive():
        nearbySheep = self.trackSheep(sheepList)
        if not nearbySheep == False:
            self.huntSheep(nearbySheep)
        else:
            self.move()
    else:
        #add death behavior later
        self.color = p.Color("black")

def main():
framerate = 30
p.init
clock=p.time.Clock()
screen=p.display.set_mode((WIDTH,HEIGHT))
screen.fill((0,0,0))
p.display.set_caption("Wolf Sheep Simulation")
running = True
#testSheep = s(5,3)
#testSheep.draw(screen)
SheepList = spawnInitialSheep()
WolfList = spawnInitialWolves()
testGrass = Grass(3,5)
spawnGrass()

while running:
    for event in p.event.get():
        if event.type == p.QUIT:
            running = False
    print(grassList)
    print(SheepList)
    for s in SheepList:
        s.update(grassList)
    for w in WolfList:
        w.update(SheepList)

    testGrass.draw(screen)
    #updte things
    #draw things
    for grassRow in grassList:
        for grassSquare in grassRow:
            grassSquare.update()
            grassSquare.draw(screen)
    for i in range (len(SheepList)):
        SheepList[i].draw(screen)
    for i in range (len(WolfList)):
        WolfList[i].draw(screen)
    p.display.flip()
    clock.tick(framerate)

p.quit()

main（）

我假设这是一个简单的格式错误，有人知道如何解决吗？

这行是baa-a-a-ad：

for s in sheepList:
    if sheepFound == 0:
        if sheepList[s].x == self.x and sheepList[s].y == self.y:    
        #  ^^^^^^^^^^^^^^
        # s is already a sheep object
            self.energy = self.energy + sheepList[s].energy

相反，您可以简单地使用sheep对象，而无需反复返回sheepList：

for sheep in sheepList:
    if sheepFound == 0:
        if sheep.x == self.x and sheep.y == self.y:    
            self.energy = self.energy + sheep.energy

类似地，在主函数中，而不是此函数中：

for i in range (len(SheepList)):
    SheepList[i].draw(screen)
for i in range (len(WolfList)):
    WolfList[i].draw(screen)

…更传统的做法是简单地写：

for sheep in SheepList:
    sheep.draw(screen)
for wolf in WolfList:
    wolf.draw(screen)

或者，进一步简化：

for animal in itertools.chain(SheepList, WolfList):
    # Watch out for wolf in sheep's clothing.
    animal.draw(screen)

谢谢现在我遇到了另一个完全不同的错误，每次程序启动后不久就会崩溃，但至少现在可以正常工作了。如果你不能解决下一个问题，你可以发布另一个问题。通常，缩小范围以形成问题的过程会导致您找到解决方案。祝你好运事实上，你有没有可能帮我解决我现在遇到的错误？编辑：Nvm我将提出一个新问题，我无法在这里正确格式化代码。
