Python: String Representation of Objects

Statement:

Implement two vehicle classes:

Car:

  • The constructor for car must take two arguments. The first of them is it's maximum speed and the second one is a string that denotes the units in which 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 the 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 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 it's 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 implementation of the classes will be tested by a provided code stub on Several input files. Each input files contain several queries.

class Car:

    def __new__(self, speed,units):
        return "Car with the maximum speed of {0} {1}".format(speed, units)

class Boat:

    def __new__(self,speed):
        return "Boat with the maximum speed of {0} knots".format(speed)
