PYTHON   Week 2 - Construct and Evaluate a Class Hierarchy Initial Post For this discussion, construct a class hierarchy for a real-life institution. Examples would be a college campus, a bank account, different types of computers, sports teams, etc. What do they have in common? What distinguishes them from one another?

Explain and give: Interface using examples. why you mighti use an Abstract class rather than an reasons

Need help implenting the classes below in Python 3 Please take a close look at the UML diagram as well as the requirements of the classes.

Design, implement and test a class that can be used to hold information about a musical note. Test it with an appropriate driver program. DESIGN REQUIREMENTS A programmer MUST be able to set and retrieve the length of the note and the value of the note. The length of a note may be a sixteenth note, eight note, quarter note, half note, or a whole note.  The note’s value is an integer. it is specified by counting how far the note lies above or below the A note that orchestras use in tuning   ( https://en.wikipedia.org/wiki/A440_(pitch_standard)  if needed to check )   . In counting "how far", you should count every key, both the white and black notes on a piano. So the A note above Middle C would have a value of 0. The A note one octave above that would have a value of 12. The default constructor should set a note to a A440 (an A note of frequency 440Hz) quarter note. Include methods to set a note to a specified length and value. Write methods to retrieve information about a note,…
