Question

I would like a method in a base class to call another method in the same class instead of the overriding method in an inherited class.
I would like the following code to print out

Class B: 6

Class A: 9

Can this be done?

---

# Base class definition
class ClassA(object):
    def __init__(self):
        print("Initializing A")

    # hoping that this function is called by this class's printFnX
    def fnX(self, x):
        return x**2

    def printFnX(self, x):
        print("ClassA:",self.fnX(x))

# Inherits from ClassA above
class ClassB(ClassA):
    def __init__(self):
        print("initizlizing B")

    def fnX(self, x):
        return 2*x

    def printFnX(self, x):
        print("ClassB:", self.fnX(x))
        ClassA.printFnX(self,x)

bx = ClassB()
bx.printFnX(3)

Answer 1

The same can be achieved by making fnX and printFnX both classmethods.

class ClassA(object):

    def __init__(self):
        print("Initializing A")

    # hoping that this function is called by this class's printFnX
    @classmethod
    def fnX(self, x):
        return x ** 2

    @classmethod
    def printFnX(self, x):
        print("ClassA:",self.fnX(x))

class ClassB(ClassA):
    def __init__(self):
        print("initizlizing B")

    def fnX(self, x):
        return 2*x

    def printFnX(self, x):
        print("ClassB:", self.fnX(x))
        ClassA.printFnX(x)


bx = ClassB()<br>
bx.printFnX(3)
