嗨，下面是我的问题的相关代码：
class Player:
def __init__(self, name, x, y, isEvil):
self.health = 50
self.attack = randint(1, 5)
self.name = name
self.x = x
self.y = y
self.isEvil = isEvil
def checkIsAlive(self):
if self.health <= 0:
return False
else:
return True
# implicit in heritance. if the child doesn't have a function that the parent has
# the functions of the parent can be called as if it were being called on the
# parent itself
class Enemy(Player):
#def __init__(self, name, x, y, isEvil):
# self.health = 50
# self.name = name
# self.x = x
# self.y = y
pass
还有更多代码：
e = Enemy('Goblin', 10, 11, True)
p = Player('Timmeh', 0, 1, False)
isLight()
while True:
if p.checkIsAlive() == True and e.checkIsALive() == True:
fight()
else:
if p.checkIsAlive() == True:
print('%s is victorious!!! %s survived with %s health points.' % (p.name, p.name, p.health))
else:
print('%s shrieks in its bloodlust!!! %s has %s health points' % (e.name, e.name, e.health))
但是，当我尝试运行此程序时，出现以下错误：
Traceback (most recent call last):
File "<string>", line 420, in run_nodebug
File "C:\Python33\practice programs\textstrat\classees.py", line 94, in <module>
if p.checkIsAlive() == True and e.checkIsALive() == True:
AttributeError: 'Player' object has no attribute 'checkIsAlive'
但是，当使用交互式控制台时，我可以这样做：
if p.checkIsAlive() == True and e.checkIsAlive() == True:
... print('they are')
...
they are
我要做的就是调用 checkIsAlive 的布尔值来确定两个对象是否发生冲突。它适用于所有其他方面，我可以只使用： if p.health <= 0 or e.health <= 0: 但是，当我还希望能够回收尽可能多的东西时，这会使我的 checkIsAlive() 方法变得毫无用处尽可能的代码。我真的无法弄清楚它为什么会这样，并且肯定很想理解它。提前感谢您的意见。
