Title: Python Tutorial: Calling Functions Inside a Class
Introduction:
In Python, classes are a fundamental part of object-oriented programming (OOP). They allow you to structure your code in a modular and organized way. Within a class, you can define functions, also known as methods, which can be called to perform specific tasks. In this tutorial, we'll explore how to call functions inside a Python class with practical code examples.
Example Class:
Let's start with a simple example class named Calculator. This class has two methods: add and multiply.
Calling Functions Inside the Class:
Now, let's demonstrate how to call these functions within the class. To do this, we'll create an instance of the Calculator class and invoke its methods.
In this example, we create an instance of the Calculator class using calc_instance = Calculator(). Then, we call the add and multiply methods on this instance, passing the required arguments.
Using self Parameter:
You may have noticed the self parameter in the method definitions (def add(self, a, b)). In Python, the self parameter is used to reference the instance of the class. It allows you to access the class's attributes and other methods within the class.
In this example, we added a new method called calculate_sum_and_product that calls both the add and multiply methods using the self parameter.
Conclusion:
Calling functions inside a Python class is a
