Get the return value from a function in a class in Python

Question

I am trying to simply get the value out of my class using a simple function with a return value, I'm sure its a trivial error, but im pretty new to python

I have a simply class set up like this:

class score():
#initialize the score info 
    def __init__(self):
        self.score = 0
        self.num_enemies = 5
        self.num_lives = 3

    # Score Info
    def setScore(num):
        self.score = num

    # Enemy Info
    def getEnemies():
        return self.num_enemies

    # Lives Info
    def getLives():
        return self.getLives

etc.....

Than I create an instance of the class as such:

scoreObj = score()

for enemies in range(0, scoreObj.getEnemies):
    enemy_sprite.add(enemy())  

I get the error saying that an integer is expected, but it got an instancemethod

What is the correct way to get this information?

Thanks!

Answer 1

scoreObj.getEnemies is a reference to the method. If you want to call it you need parentheses: scoreObj.getEnemies().

You should think about why you are using a method for this instead of just reading self.num_enemies directly. There is no need for trivial getter/setter methods like this in Python.
