call function without parenthesis in python





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

what modification i would need to do in the below function computeDifference to get result printed in the console, instead of object message.



i know i need to add parenthesis () to call function to get the result printed in the console, but is there any other way to print the result? 



class Difference1:

    def __init__(self, a):

        self.__elements = a



    def computeDifference(self):

        self.difference =  max(self.__elements)- min(self.__elements)

        return self.difference



a = [5,8,9,22,2]

c = Difference1(a)

print(c.computeDifference)





python oop

          Make it a property



          class Difference1:
          
@property
          
def computeDifference(self):
          
   ...
          

          
print(c.computeDifference)


          However, I would change the name to difference. The idea of a property is that you shouldn't know or care whether the value is computed at that time or is stored as an attribute of the object. See uniform access principle.

            You could add a magic function:



            class Difference1:
            
    ...
            
    def __str__(self):
            
        return self.computeDifference()
            
    ...
            

            
>>> a = [5,8,9,22,2]
            
>>> c = Difference1(a)
            
>>> print(c)
