For the following question, refer to the Python module on the right, as well as the code below. 1) What is the output of the following code? #dodgeable.py #main dodgeable.py import dodgeable class Locatable: def NUM_CARS = 3 init (self,x,y): NUM TRUCKS = 2 self.mX = X WIDTH = 60 self.mY = y def setx (self,x): def main (): self.mX = x object_list = [] def sety (self, y): self.mY = y for i in range (NUM_CARS) : x = WIDTH/NUM CARS * i def getx(self): return self.mx y = 50 c = dodgeable.Car (x, y, 10) def getY(self): object_list.append(c) return self.my for i in range (NUM_TRUCKS): x = WIDTH/NUM TRUCKS * i class Movable (Locatable): def init (self, x, y, dx, dy) : t = dodgeable.Truck (x, y,5) Locatable. init (self,x,y) object_list.append(t) self.mDX = dx count = 0 self.mDY = dy for ob in object_list: print (count, ": before ", ob.getX(), ob.getY()) def move (self): ob.move() self.setx (self.getX() +self.mDX) print (count, ": after",ob.getX(), ob.getY()) self.sety (self.getY() +self.mDY) count += 1 main() class Car (Movable): def init (self,x,y, speed): Movable. __init__(self,x,y, speed, 0) self.mSpeed = speed y = 100 Write the output here: class Truck (Movable): def init (self,x,y, speed): Movable. init (self,x,y, speed, 0) self.mSpeed = speed

Here is the output of the question 1

0 :before 0.0 50 0 :after 10.0 50 1 :before 20.0 50 Ki :after 1 :after 30.0 50 2 :before 40.0 50 2 :after 50.0 50 3 :before 0.0 100 3 :after 5.0 100 4 :before 30.0 100 4 :after 35.0 100 ... Program finished with exit code 0 Press ENTER to exit console.

Now explanation of the output is given below

[con (0,150,16]. list, have. We given 4 classes. code. the Locatable, Movable, car and truck. Now with the main lets start functions Initially. NUM CARS = 3 NOM TRucks = a. WIDTH = 60 object_list = [ ] Now, frost for look times. for izo, 1 Now. will 2 3 and 2. O 60/34.0 it will make car object- c= dodgeable, car (0,50,10) a objectlist. appena (c) E It will append the object in object bject list becomes 21 2o n= 6013*1 y so car object with h=2014 avo object- list becomes a [cax 20, 50, 10), car (20, 50, 10)

Similarly 122. whee So, When object of value n = 40, 4250 append to the list. after checuting first four look- list [car (0, 50,10), Can (2005 car (40,50,10)]. object becomes Now, is it similler. will add- Second first for object for loop loole but into the 2 times truck object liste gt will run for 120, Truck co, 100,5) will be adocd to the list. be for iz) Truck (30,100,5) added the will list. Now, Not object list becomes. [car (0,50,10), Cas (20,50,10), car (40,50, 10), truck co, 100,5), truck (30,100,5).

fox ob in scan object list: & It will each object in object list. point (count," before", ob. getxu, ob.getY(J) fetch & fetch y value. --- Value ob. move. Co z This will simply ado- 3 parameter to h, and o loc. This look Car (60,50,10) becomes - (10,50,10) Truck co, loo, 5) becomes (5, 100,5) will print before updation valec of and Naluc. y with count increas every iteration. and after n after
