Question
Python
Write a python program to define a class (Clock) with the following members:
> Attributes:
hours: default = 0
minutes: default = 0
seconds: default 0
> Methods:
_init_: a parameterized constructor with defaults values.
getHours: returns hours.
getMinutes: returns minutes.
getSeconds: returns seconds.
setTime: changes the time (hours, minutes, seconds) to new values [it's better to
have 3 set methods].
• show: prints time in this format 00:00:00.
• add (s, m, h): add times (+).
sub (s, m, h): subtract times (-).
Define two classes (Traditional Clock) and (Smart Clock) that are inherited from class (Clock)
with the following members:
(Traditional Clock) Attributes:
• color: default = "Red"
(Traditional Clock) Methods:
• getColor: returns the color.
setColor: changes the color.
show: prints time in this format 00:00:00 plus class name.
(Smart Clock) Attributes:
• specialFeature: default = "Alarm activation"
(Smart Clock) Methods:
get specialFeature: returns the special feature.
• set specialFeature: changes the special feature
show: prints time in this format 00:00:00 plus class name.
Testing Code:
Create objects from: Clock, Traditional Clock, and Smart Clock classes with these
values:
Second
Minute
Hours
Clock Object
2 Color(Blue)
Traditional Clock Object
Smart Clock Object
20
30
15
22
5
Change color attribute of Traditional Clock Object to "Blue",
Assign the previous values for attributes in both Traditional and Smart Clock
Classes.
Call Get Methods for all data attributes in all classes.
Call add and sub methods for Traditional Clock Object with the following values
(10, 20, 3), (5, 3, 1) and for Smart Clock Object with the following values (35, 25,
4), (10, 20, 2).
Call show method for all objects.

Output:
Clock Class seconds are: 0 , Minutes are: 0 , Hours are: 0
Time in Clock Class is:
0 : 0 : 0
Traditional Clock Class seconds are: 20 ,
Minutes are: 30 ,
Hours
are: 2
Time in Traditional Clock Class is:
25 : 47 : 4
Smart Clock Class seconds are: 15 , Minutes are: 22
Hours are: 5
Time in Smart Clock Class is:
