python-3.x - 属性错误 : 'function' object has no attribute

Question

我一直在尝试制作一款游戏，但是这个错误一直出现。我是 python 的初学者，所以我希望你们甚至可以看看这个可怕的代码。

AttributeError: 'function' object has no attribute 'armorEquipped'

我对这意味着什么感到非常困惑，但有人可以向我解释一下吗？

normalarmor={
"TRAINING ARMOR":["Armor meant for training","no element", +10, " health"]}

firearmor={
    "LIGHTBRINGER":["Armor that brings light", "Fire element", +10, " health, Grass type deals less damage"]}

                        print ("That is not a valid answer")
                        z=True

它在这里搞砸了:

def tutorial():
    x=True
    uhealth= normalarmor[equipArmor.armorEquipped][2]+uhealth 

为什么会出现这个问题，这是什么问题？
请帮我 !

Answer 1

首先，让我们切入追逐场景。尽管它可能出现在函数内的函数属性中，但这并不符合人们的预期。但是，可以在外部设置函数的属性。

>>> def f():
...     f.a = 1
...     return 42
... 
>>> f.a
Traceback (most recent call last):
  File "<interactive input>", line 1, in <module>
AttributeError: 'function' object has no attribute 'a'
>>> f.b = 2
>>> f.b
2

虽然我不清楚你想完成什么，但可能是 __call__可能会这样做。现在这个对象class表现得像一个函数，同时，该函数可以设置对象的属性。

>>> class EquipArmour:
...     def __call__ (self, param):
...         if param == 1:
...             self.armourEquipped = 52
...         else:
...             self.armourEquipped = -34
... 
>>> equiparmour = EquipArmour()
>>> result = equiparmour(1)
>>> if equiparmour.armourEquipped == 34:
...     'say hello'
...
