Python class method merge

Is it possible to merge two classes' methods like so?

class foo:
    def __init__(self):
        self.active = False
    def doThing(self):
        if not self.active: return
        print("Just a foo here, boss")

class bar(foo):
    def __init__(self):
        self.active = False
    def doThing(self):
        print("I shouldn't be showing unless I'm active!")

f = foo()
b = bar()
f.doThing()
b.doThing()

This will output "I shouldn't be showing unless I'm active!" when I want it to inherit the self.active checking part of the parent class and thus make the method return before the rest of it runs. Is there a way to do this?

The other answers are correct, merging the functions does not make any sense. Though if you want to implement the second class and merge it in an OOP manner, the code is below.

class Bar(Foo):
def __init__(self):
    super().__init__()

def doThing(self):
    super(self).doThing()
    if not self.isActive(): return
    print("I shouldn't be showing unless I'm active!")

You can put the check in a separate function:

class Foo:
    def __init__(self):
        self.active = False

    def isActive(self):
        return self.active

    def doThing(self):
        if not self.isActive(): return
        print("Just a Foo here, boss")

class Bar(Foo):
    def __init__(self):
        super().__init__()

    def doThing(self):
        if not self.isActive(): return
        print("I shouldn't be showing unless I'm active!")

Or alternative:

class Foo:
    def __init__(self):
        self.active = False

    def doThing(self):
        if not self.active: return
        return self.doPrint()

    def doPrint(self):
        print("Just a Foo here, boss")

class Bar(Foo):
    def __init__(self):
        super().__init__()

    def doPrint(self):
        print("I shouldn't be showing unless I'm active!")
