) Python command line menu-driven application that allows a user to display, sort and update, as needed a List of U. S states containing the state capital, overall state population, and state flower. The Internet provides multiple references with these lists. For example:

Explanation:

The following is a Python program that creates a menu as requestes. The menu allows the user to choose to display list, sort list, update list, and/or exit. A starting list of three states has been added. The menu is on a while loop that keeps asking the user for an option until exit is chosen. A sample output is shown in the attached picture below.

states = {'NJ': ['Trenton', 8.882, 'Common blue violet'], 'Florida':['Tallahassee', 21.48, 'Orange blossom'], 'California': ['Sacramento', 39.51, 'California Poppy']}

while True:

   answer = input('Menu: \n1: display list\n2: Sort list\n3: update list\n4: Exit')

   print(type(answer))

   if answer == '1':

       for x in states:

           print(x, states[x])

   elif answer == '2':

       sortList = sorted(states)

       sorted_states = {}

       for state in sortList:

           sorted_states[state] = states[state]

       states.clear()

       states = sorted_states

       sorted_states = {}

   elif answer == '3':

       state = input('Enter State: ')

       capital = input('Enter Capital: ')

       population = input('Enter population: ')

       flower = input('Enter State Flower: ')

       states[state] = [capital, population, flower]

   else:

       break
