Question 3. [16 MARKS] Part (a) [4 MARKS Complete the Car class below. class Car: A Car class. we Attributes plate: this car's license plate number odometer: how many km this car has been driven in total plate: str odometer: int # TO DO: COMPLETE THE INITALIZER BELOW def __init__(self, plate: str) -> None: "Initialize a new Car with the given <plate>, and Okm on the odometer. >>> ci - Car ("AAA 111") >>> c1.plate "AAA 111" >>> ci.odometer # TO DO: COMPLETE THE drive METHOD BELOW (INDICATE THE EXPECTED DATA TYPE OF ANY PARAMETERS) def drive(-- _) -> int: Update the odometer by the given <distance>, a number which represents the distance driven. If distance is negative, the odometer is not modified. Return the updated odometer value. >>> C - Car("AAA111") >>> c.drive (10) 10 >>> c.drive (33) >>> c.drive(-12)

-------------------------------------------------------

class Car:
plate: str
odometer: int
  
# constructor
def __init__(self, plate: str) -> None:
# assign class attribute with the given plate
self.plate = plate
# assign 0 to class attribute using self
self.odometer = 0

c1 = Car("AAA111") # object creation with parameterized constructor
print(c1.plate) # print plate value
print(c1.odometer) # print odometer value

-------------------

Code and result :

1* class Car: plate: str odometer: int # constructor def _init_(self, plate: str) -> None : # assign class attribute with the given plate self.plate = plate # assign e to class attribute using self self.odometer = 0 6- 8. 10 11 # object creation with parameterized constructor # print plate value # print odometer value c1 = Car("AAA111") print(c1.plate) print (c1.odometer) 12 13 14 Execute Mode, Version, Inputs & Arguments 3.7.4 Interactiv CommandLine Arguments • Execute Result executed in 0.976 sec(s) AAA111

code :

class Car:

odometer: int
  
# constructor
def __init__(self, plate: str) -> None:
# assign class attribute with the given plate
self.plate = plate
# assign 0 to class attribute using self
self.odometer = 0
  
# drive method - updates odometer value
# method takes distance parameter with data type 'int'
def drive(self, distance: int) -> int:
if(distance > 0): # if value is positive then modify odometer value
# adds given distance value to class attribute 'odometer'
self.odometer = self.odometer + distance
  
return self.odometer
  

c = Car("AAA111") # object creation with parameterized constructor
print(c.drive(10)) # print odometer value
print(c.drive(33)) # method call using object and print the returned value
print(c.drive(-12))
