2. Python: String Representations of ObjectsImplement two vehicle classes: Car:The constructor for Car must take two arguments. The first of them is its maximum speed, and the second one is a string that denotes the units in which the speed is given: either "km/h" or "mph".The class must be implemented to return a string based on the arguments. For example, if car is an object of class Car with a maximum speed of 120, and the unit is "km/h", then printing car prints the following string: "Car with the maximum speed of 120 km/h", without quotes. If the maximum speed is 94 and the unit is "mph", then printing car prints in the following string: "Car with the maximum speed of 94 mph", without quotes. Boat:The constructor for Boat must take a single argument denoting its maximum speed in knots.The class must be implemented to return a string based on the argument. For example, if boat is an object of class Boat with a maximum speed of 82, then printing boat prints the following string: "Boat with the maximum speed of 82 knots", without quotes. The implementations of the classes will be tested by a provided code stub on several input files. Each input file contains several queries, and each query constructs an object of one of the classes. It then prints the string representation of the object to the standard output.

Solution
Here is a step-by-step solution to implement the Car and Boat classes in Python:
Step 1: Define the Car class with a constructor that takes two parameters: maximum speed and unit of speed. The constructor should initialize these values.
Step 2: Define the __str__ method for the Car class. This method should return a string that describes the car in the required format.
Step 3: Define the Boat class with a constructor that takes one parameter: maximum speed. The constructor should initialize this value.
Step 4: Define the __str__ method for the Boat class. This method should return a string that describes the boat in the required format.
Here is the Python code that implements these steps:
class Car:
def __init__(self, max_speed, speed_unit):
self.max_speed = max_speed
self.speed_unit = speed_unit
def __str__(self):
return f"Car with the maximum speed of {self.max_speed} {self.speed_unit}"
class Boat:
def __init__(self, max_speed):
self.max_speed = max_speed
def __str__(self):
return f"Boat with the maximum speed of {self.max_speed} knots"
You can use these classes like this:
car = Car(120, "km/h")
print(car) # prints: Car with the maximum speed of 120 km/h
boat = Boat(82)
print(boat) # prints: Boat with the maximum speed of 82 knots
This code defines two classes, Car and Boat, each with a constructor and a __str__ method. The __str__ method is a special method in Python that returns a string representation of an object. When you print an object, Python calls this method to determine what to print.

Problem StatementKaniska is tasked with creating a program that allows users to input information about different types of vehicles and calculate the time it takes for these vehicles to travel a given distance at their maximum speeds. The program will support three types of vehicles: Cars, Bicycles, and Boats.Your task is to implement the Vehicle class as the base class for these three vehicle types. The Vehicle class should have the following properties and functionalities:Properties:numOfWheels (integer): representing the number of wheels of the vehicle.maxSpeed (floating-point): representing the maximum speed of the vehicle.Functionalities:A default constructor to initialize numOfWheels and maxSpeed to 0.A virtual function setNumOfWheels(int wheels) to set the number of wheels of the vehicle.A virtual function setMaxSpeed(float speed) to set the maximum speed of the vehicle.A virtual function getNumOfWheels() to get the number of wheels on the vehicle.A virtual function getMaxSpeed() to get the maximum speed of the vehicle.A virtual function timeToTravel(float distance) that calculates and returns the time it takes for the vehicle to travel the given distance at its maximum speed.Implement three derived classes, Car, Bicycle, and Boat, which inherit from the Vehicle class. Each derived class should override the timeToTravel(float distance) function with the appropriate calculation for the specific vehicle type. The Car and Bicycle classes should calculate the time based on their maximum speed in mph, while the Boat class should consider the maximum speed in knots and convert it to mph using the formula 1 knot = 1.151 mph.In the main function, create instances of each vehicle type (Car, Bicycle, and Boat) and take user input for the number of wheels and maximum speed for each vehicle. Then, the user will input a distance, and the program will display the details of each vehicle and the time it takes for each vehicle to travel the given distance at its maximum speed.Note: This kind of question will help in clearing Capgemini recruitment.Input format :The first line consists of the number of wheels and the maximum speed of the car, separated by a single space.The third line consists of the number of wheels and the maximum speed of the bicycle, separated by a single space.The fifth line consists of the maximum speed of the boat (in knots).The sixth line consists of the distance to travel (in miles).Output format :The program outputs the details of the car, bicycle, and boat, including the number of wheels and the maximum speed for each vehicle, as well as the time it would take to travel the specified distance at maximum speed.The output includes the vehicle type, number of wheels, maximum speed, and time taken to travel the distance.The time taken is displayed in hours.Refer to the sample input and output for format specifications.Code constraints :The number of wheels (numOfWheels) for each vehicle is a positive integer.The maximum speed (maxSpeed) for each vehicle is a positive floating-point number.The distance to travel is a positive floating-point number.The maximum speed of the Boat (in knots) should be converted to mph using the formula: 1 knot = 1.151 mph.Sample test cases :Input 1 :4 602 153050Output 1 :Vehicle Details:Car has 4 wheels and can go up to 60 mph. It would take 0.833333 hours to travel 50 miles at maximum speed.Bicycle has 2 wheels and can go up to 15 mph. It would take 3.33333 hours to travel 50 miles at maximum speed.Boat has 0 wheels and can go up to 30 knots. It would take 1.44802 hours to travel 50 miles at maximum speed.Input 2 :4 902 203575Output 2 :Vehicle Details:Car has 4 wheels and can go up to 90 mph. It would take 0.833333 hours to travel 75 miles at maximum speed.Bicycle has 2 wheels and can go up to 20 mph. It would take 3.75 hours to travel 75 miles at maximum speed.Boat has 0 wheels and can go up to 35 knots. It would take 1.86174 hours to travel 75 miles at maximum speed.Note :The program will be evaluated only after the “Submit Code” is clicked.Extra spaces and new line characters in the program output will result in the failure of the test case.
Problem 2: Classes and Objects Scenario: Write a Python program to implement the concept of classes, methods, and objects. Instructions: Create a Python Class named “Vehicle.” This Class will have a total of five (5) attributes and one (1) method, as follows: o Attributes: type, total_seats, color, price, mileage o Method: print_detail() If the total number of seats in a vehicle is more than seven (7) and the price is more than $50,000, print “It is an unaffordable vehicle.” Otherwise, print “You may afford and easily park it.” Create the following four (4) vehicle objects: bus, bike, car, and pickup_truck. For each object, take the attribute value from the user. This means the user will enter all five (5) attribute values for each object. Assign these values to the related object and print all the details one by one.
