Python - Obtaining value from a boolean function without accessing it

Question

When needing the output of a function such as:

def _hasWon(self):
   if self == True
      return True
   else 
      return False

Then later setting this via:

self._hasWon(True)

But if I need to check if _hasWon is True later, how would I check it without calling the function? I currently have:

if self._hasWon(self)

This calls the function again, however, which will change the existing value. How should this be rewritten?

You are probably doing something wrong here.

If you are using a class, you could something like

Class MyClass:
    def hasWon(self, won):
        self.won = won # won is bool

Now set the value like this

obj = MyClass()
obj.hasWon(True)

And get the value as

obj.hasWon

You have an option to keep the state in the function, but using a class seems to be more common solution

def _hasWon(self, previous=[]):
    if not previous:
        previous.append(self)
    return next(iter(previous))

It will return the first value got passed until you pass an empty list as a second argument to set a new state
