8. Update Entries in a Dictionary

Dictionary entries can be modified or updated. If our person Lisa has a birthday, then her age needs to be updated. To update her age simply use the age key and assign a new value:

person[age]=30 

The resulting dictionary could be viewed as:

{name:Lisa, age:30, 'school:SNHU}

RUN THE CODE TO THE LEFT

{'age': 29, 'school': 'SNHU', 'name': 'Lisa'} {'age': '30', 'school': 'SNHU', 'name': 'Lisa'}
