You can override a method in a child class by defining a new method with the same name in the child class. When an instance of the child class calls the overridden method, the child class's version of the method will be called instead of the parent class's version.
Here's an example:
class Animal:
def make_sound(self):
print("Generic animal sound")
class Cat(Animal):
def make_sound(self):
print("Meow")
class Dog(Animal):
def make_sound(self):
print("Woof")
my_animal = Animal()
my_animal.make_sound() # Output: "Generic animal sound"
my_cat = Cat()
my_cat.make_sound() # Output: "Meow"
my_dog = Dog()
my_dog.make_sound() # Output: "Woof"
In this example, we define a parent class Animal with a method make_sound() that prints a generic animal sound. We then define two child classes Cat and Dog, each of which overrides the make_sound() method with its own implementation.
When we create an instance of Cat or Dog and call the make_sound() method, the appropriate version of the method is called based on the instance's class. If we create an instance of Animal and call make_sound(), the parent class's version of the method is called.
