Hint

Use if statements and elif to manage testing for the different age ranges.

Exercise 1f​

References:

Extend your code from Exercise 1e to do the following:

  • ask for the user's annual income;
  • the term 'annual income' should have a pop-up that defines what annual income means;
  • If the user inputs an income, it should be displayed in the final screen as currency (hint: use the currency() function)
  • If the user inputs an income of $0, then the text 'you do not earn an income' should be displayed in the final screen.
Example output

Hello Hansel Forrest, you are an adult and your annual income is $45,000.

Exercise 1g​

Extend your code from Exercise 1f to do the following:

  • ask if the user has a partner;
  • if the user has a partner, then ask for the partner's name and partner's income;
  • display the total household income (which is the sum of the two incomes) on the final screen;
  • display the average household income on the final screen
Example Output

Hints
  • You can use show if to display the partner details if the user has a partner
  • Remember to account for the case when the user does not have a partner when you create the total household and average household incomes - have another look at Video C1.06
