How do I inherit classes in Python?

In Python, you can inherit classes by defining a new class that takes the parent class as a parameter. For example:

class Parent:
    def greet(self):
        return "Hello from the Parent class!"

class Child(Parent):
    pass

child_instance = Child()
print(child_instance.greet())  # Output: Hello from the Parent class!

What if I want to override a method in the child class?

You can override a method by defining a method with the same name in the child class. For example:

class Child(Parent):
    def greet(self):
        return "Hello from the Child class!"

child_instance = Child()
print(child_instance.greet())  # Output: Hello from the Child class!

Can a child class call a method from the parent class?

Yes, you can call a parent class method using super(). For example:

class Child(Parent):
    def greet(self):
        return super().greet() + " And hello from the Child class!"

child_instance = Child()
print(child_instance.greet())  # Output: Hello from the Parent class! And hello from the Child class!
