AttributeError: 'function' object has no attribute

Question

I've been trying to make a game, but this one error keeps appearing. I'm a beginner in python so I hope you guys can even look at this horrendous code.

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

I'm very confused on what this means but could someone explain it to me?

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

and it messes up around here:

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

Why is this problem appearing and what is this problem? Please help me !

How is `equipArmor` defined in the code? – Bill Bell Jul 14 '17 at 17:43 — Bill Bell, Jul 14 '17 at 17:43
Oh oops I forgot to share the main bulk of the code. Sorry! – ypranite Jul 14 '17 at 18:08 — ypranite, Jul 14 '17 at 18:08

First of all, let's cut to the chase scene. Although it might appear an attribute of a function within the function this doesn't do what one might expect. The function's attributes can, however, be set outside.

>>> 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

Although I'm not clear about what you want to accomplish it might be that __call__ might do it. Now an object of this class behaves like a function and, at the same time, the function can set attributes of the object.

>>> 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'
...

I don't exactly get your answer. I'm not really sure what __call__ does — ypranite, Jul 14 '17 at 21:10
`__call__` is one of Python's special names inside an object. In this code where I wrote `equiparmour(1)` it's practically like writing `equiparmour(1).__call__(1)`. But the lovely thing is that `equiparmour` is an **object**. Unlike a function it can have properties (and other methods). This means that although I couldn't set a property such as `armourEquipped` in a function I **can** in an object. Yet I can still use that object like a function. I get something from both worlds, which is what you wanted in the first place. If this isn't clear yet keep asking. — Bill Bell, Jul 14 '17 at 21:31

@TheGamerCow I've got a 24" screen but your code ran off it.

I've replaced it like this:

 if (equipArmor.armorEquipped in normalarmor or
        equipArmor.armorEquipped in waterarmor or
        equipArmor.armorEquipped in firearmor or
        equipArmor.armorEquipped in airarmor or
        equipArmor.armorEquipped in grassarmor):

Check for styling at: multiline conditions
