Difference Between Overloading And Overriding In Python
In Python, overloading and overriding are concepts related to method definitions in classes. Overloading refers to defining multiple methods in a class with the same name but different parameters, allowing for different ways of calling the method. When a method is called, Python determines which version of the method to execute based on the number and type of arguments provided. On the other hand, overriding involves defining a method in a subclass that has the same name and parameters as a method in the superclass. By doing this, the subclass provides a new implementation for the method, effectively replacing the behavior inherited from the superclass. Overloading is determined at compile time, while overriding is determined at runtime based on the object being used.

1 - Overloading and Overriding are two concepts in object oriented programming that involve creating multiple methods with the same name, but with different implementations or behavior.
2) Overloading refers to the ability to define multiple methods in a class with the same name, but different parameters. This allows a method to perform different tasks based on the input arguments provided.
3) In Python, method overloading is not supported in the traditional sense as it is in languages like Java or C++. Instead, developers can achieve similar behavior by using default parameter values or using variable length argument lists.
4) Overriding, on the other hand, is the ability to provide a new implementation for a method that is already defined in a parent class. This allows a subclass to provide a specialized implementation for a method that is inherited from a parent class.
5) When a method is overridden in a subclass, the method in the parent class is replaced by the new implementation in the subclass. This allows for polymorphic behavior, where different objects can be treated as instances of the same class but exhibit different behaviors based on their actual class types.
6) In Python, method overriding is a common practice when working with inheritance. Subclasses can provide their own implementation for methods defined in a parent class, enabling greater flexibility and customization.
7) Training programs for students interested in learning about overloading and overriding in Python should cover the fundamental concepts, demonstrate practical examples, and provide hands on exercises to reinforce learning.
8) Students should understand the differences between overloading and overriding, as well as when and how to apply each concept effectively in their Python programs.
9) By mastering overloading and overriding in Python, students can improve their object oriented programming skills, design more robust and flexible classes, and leverage the power of inheritance to create reusable and extensible code.
10) In summary, overloading allows for multiple methods with the same name but different parameters, while overriding enables subclasses to provide their own implementations for methods inherited from parent classes. Both concepts are important tools in the Python developer's toolkit and should be learned and practiced to become proficient in object oriented programming.
