### method overriding in python
**introduction to method overriding**
method overriding is a feature in object-oriented programming where a subclass provides a specific implementation of a method that is already defined in its superclass. the new method in the subclass has the same name, parameters, and return type as the method in the parent class. this allows the subclass to provide a specialized behavior for that method.
**why use method overriding?**
- to provide specific implementations of methods in subclasses.
- to enhance or modify the behavior of inherited methods.
- to follow the principle of polymorphism in object-oriented design.
### basic concepts
1. **superclass (parent class)**: the class from which properties and methods are inherited.
2. **subclass (child class)**: the class that inherits properties and methods from the superclass and can override them.
### method overriding syntax
### example of method overriding
let's demonstrate method overriding with a practical example using a `vehicle` superclass and a `car` subclass.
### explanation of the example
1. **vehicle class**: this is the parent class with a method `start_engine()`.
2. **car class**: this subclass overrides the `start_engine()` method to provide a more specific implementation for cars.
3. **motorcycle class**: another subclass that overrides the same method for motorcycles.
4. **creating instances**: we create instances of `car` and `motorcycle` and call their `start_engine()` methods, which exhibit the overridden behavior.
### key points
- when a method in a subclass overrides a method in its superclass, the subclass method is called when an object of the subclass invokes the method.
- the `super()` function can be used to call the parent class's method if needed, allowing for a combination of the parent and child class behaviors.
### using `super()` in method overriding
you can still access the method in the superclass using the `super()` function. here’s how you ...
