The place where change happens.
In this Lab, we will work with classes.
The task / data we use: Create a class to hold information about music tracks / songs on a CD / music album. (position, title, length)
One note about testing: Make sure to test that the script works as expected (with ‘good’ values).
But also think about what values to use to test that you can’t break your script.
These tests typically are more efficient.
