: Please notice that the function named sec_to_time() did not get moved under the class block. It remains as an external function.
:1. Create a new python file and name it as '''lab7d.py''' and , place the code listed above in it, and change '''sum_times()''' and '''change_time()''' functions from lab7c.py to become object methods for our Time object.
:2. Save the file, and test the new time object in an interactive Python shell: <source lang="bash">
[rchan@centos7 lab7]$ python3
