Transcribed Image Text:Question 2 Define a Car class that instantiates objects that mimic the behavior of motor cars. The constructor of this class will initialize the following instance attributes, with the default values indicated: brand = 'Ford', color = 'red', driver = 'person', speed = 0. When we instantiate a new Car object (), we can choose its brand and color, but not its speed, nor the name of its driver. The following methods will be defined: • choice_driver (name) will be used to designate (or change) the name of the driver. %3D accelerating (rate, duration) will vary the speed of the car. The speed variation obtained will be equal to the product: rate x duration. For example, if the car accelerates at the rate of 1.3 m /s for 20 seconds, its speed gain should be 26 m / s. Negative rates will be accepted (which will make it possible to decelerate). Speed variation will not be allowed if the driver is a 'nobody'. display_all () will display the current properties of the car, ie its brand, color, driver's name, speed. • Add the _repr_ and _eq_ methods (second picture)

def
repr
(self):
(Temps)-> str'''
return (str(self.heure) +":" +str(self.minute) +":" +str(self.seconde))
def
(self, autre):
eq
''" (Temps) -> bool''!
return self.heure == autre.heure and self.minute == autre.minute and self.se
