Question

Design a Racing Car that can be used in a game and the Car must be able to be started, run, and stopped in Eclipse along with a UML. 1. The Car must have an Engine and Tires. 2. The Car must have four Tires. 3. The Car must have one Engine. 4. The Engine must be able to be started and stopped. 5. Before the Engine can be started all Tires must have at least 32 psi. 6. The Car must be able to be started, running between 1 and 60 mph, stopped, and also be able to be restarted.

Answer 1

class Car:
Engine=1
tyres=4
speed=0
def __init__(self, Engine, tyres, speed):
self.Engine = Engine
self.tyres = tyres
self.speed = speed

#methods
def start(self,speed,tyre_pressure):
if int(tyre_pressure)>=32:
self.speed +=int(speed)
if int(self.speed)>60:
self.speed=60
print 'Car running at speed:'+str(self.get_speed())
print '-----------------------------------------------------------'
print 'Maximum speed achieved. cannot increase more.'
print '-----------------------------------------------------------'
else:
print 'Car started at speed:'+str(self.get_speed())
print '-----------------------------------------------------------'

else:
print 'Increase air pressure in tyres'
print '-----------------------------------------------------------'

def stop(self):
self.speed=0

def get_speed(self):
return self.speed

def main():

Engine = raw_input('Enter the car Engines: ')
tyres = raw_input('Enter the car Tyres: ')
speed = 0

mycar = Car(Engine, tyres, speed)

#Start
run=int(raw_input("Enter 1 if you want to run the car: "))
print('*************************************************************')

if (run==1):
while(True):
speed=raw_input('Increase speed by :')
tyre_pressure=raw_input('Enter tyre pressure: ')
print('*************************************************************')

mycar.start(speed,tyre_pressure)
print "Enter 0 if you want to stop the car or 1 to continue."
print('*************************************************************')
run=int(raw_input())
if run==0:
break
else:
print('Car is steady')
print('*************************************************************')

mycar.stop()
print 'The current speed after brake is: ', mycar.get_speed()
print '-----------------------------------------------------------'

#Call the main function
main()
