A Beginner's Guide to Inheritance in Python: Understanding and Implementing OOP Concepts

In Python, inheritance allows a new class to be created that is based on an existing class. The new class, called the child class, inherits properties and methods from the existing class, called the parent class.

For example, let's say we have a parent class called "Animal" with a method called "speak" that simply returns the string "Animal can speak.".

class Animals:
    def speak(self):
        return "Animals can speak."

We can create a child class called "Dogs" that inherits from the "Animals" class. The "Dogs" class will have access to the "speak" method from the parent class.

class Dogs(Animals):
    pass

Now we can create an instance of the "Dogs" class and call the "speak" method.

dog = Dogs()
print(dog.speak())

This will output "Animals can speak.". This is because the "speak" method was inherited from the parent "Animals" class.

We can also override the inherited method in child class to give a different behavior.

class Dogs(Animals):
    def speak(self):
        return "Dogs bark."

Now when we call the speak method on Dogs class instance, it will return "Dogs bark."

dog = Dogs()
print(dog.speak())

This will output "Dogs bark."

Inheritance is a powerful feature of object-oriented programming that allows for code reuse and a logical class structure.
