Question

Part 3 (25 points) Query the dictionary you created Save your completed program happy2.py as happy3.py and comment out the call to the print_sorted_dictionary() in the main() function. You will complete the function lookup_happiness_by_country() that is passed the dictionary as an argument. Uncomment this function and complete the code so that your program uses an indefinite while loop to repeatedly ask the user for a country to look up in the dictionary. The input prompt is: Enter a country to lookup or 'done' to exit: If a country is in the dictionary your program will print the happiness index Enter a country to lookup or 'done' to exit:Mexico 6.549578667 If a country is not in the dictionary, your program will print that country name was not found. Enter a country to lookup or 'done' to exit:Atlantis Atlantis not found If the user just enters done, your program should simply return from the function call. Enter a country to lookup or 'done' to exit: done Below is an example of how your program should work. Make sure it matches this example before submitting it to Gradescope.
