1.       (Account Class with Read-Only Properties)   Modify Section 10.2.2’s Account class to provide read-only properties for the name and balance. Rename the class attributes with single leading underscores. Re-execute Section 10.2.2’s IPython session to test your updated class. To show that name and balance are read-only, try to assign new values to them.

2.       (Time Class Enhancement)   Modify Section 10.4.2’s Time class to provide a readonly property universal_str that returns a string representation of a Time in 24-hour clock format with two digits each for the hour, minute and second, as in '22:30:00' (for 10:30 PM) or '06:30:00' (for 6:30 AM). Test your new read-only property
