The Time class stores two integers representing the starting time of an activity and the ending time of an activity in a PE lesson.
For example, if an activity starts at 13:17 and finishes at 13:25, the values 17 and 25 are stored.
The start number can never be less than 0 and the end number can never be greater than 60.
A Time object can be constructed as follows:
t = Time(17,25)
Design the Time class, including accessor methods for both the start and end properties.
Test you design by writing a program that constructs a Time object and displays the start and end time stored.
Note: you do not have to write validation code. We will do that in Task 2.
Save your solution as time-1.py
Write a program that will use the following information to construct 5 time objects and append them into an array with global scope.
The array should have a lower bound of 0 and an upper bound of 4 when complete.
When the user is entering the data, include validation techniques that will not allow the user to enter data that is less than 0 or greater than 60.
| activity | start | end |
|---|---|---|
| 1 | 0 | 13 |
| 2 | 15 | 19 |
| 3 | 23 | 31 |
| 4 | 37 | 43 |
| 5 | 49 | 56 |
Save your solution as time-2.py
In your program, implement a function that calculates and returns the total time of all activities in the global array of Time objects.
For example, using the above data, the function should return (13-0) + (19-15) + (31-23) + (43-27) + (56-49) = 48
Save your solution as time-3.py
Write pseudocode, including the function header for your solution to Task 3.
Make sure you are thoughtful when testing your solution.
If your code has a validation check, test your code with acceptable/valid data and unacceptable/invalid data.
