The dealership sells different types of vehicles: cars and trucks. All vehicles have a make, model, and year. However, a truck has an additional attribute - maximum load capacity (in pounds). Create a class named Vehicle with the following attributes: make, model, and year. Include the following methods: display_info(): This method should print all these details in a formatted string. get_age(): This method should calculate and return the age of the vehicle based on the current year. Tip: You will need to import functionality from the datetime module to do this. Create a class named Truck that inherits from the Vehicle class. This class should have an additional attribute, max_load, which represents the maximum load capacity of the truck. Include the following methods: display_info(): This method should override the method from Vehicle, and when it's called, it should display the truck's make, model, year, and maximum load capacity. can_carry(weight): This method should take a weight (in kilograms) as an argument and return a boolean indicating whether the truck can carry the given weight. Instantiate at least one Vehicle and one Truck object. Call the display_info(), and get_age() methods on both to ensure they are working as expected. Then call can_carry() on the Truck object only. See if the truck can carry 11,000 lbs.

OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
