Question

Browse the web to locate the lyrics to the song “The Twelve Days of Christmas.” The song contains a list of gifts received for the holiday. The list is collective so that as each “day” passes, a new verse contains all the words of the previous verse, plus a new item. Write an application that displays the words to the song starting with any day the user enters. (Hint: Use a switch statement with cases in descending day order and without any break statements so that the lyrics for any day repeat all the lyrics for previous days.)

True or False: Adding more control variables will always increase the R 2 value. True False

switch_player(): we will allow the players to choose their own names, but for our purposes, it is easier to think of them as number (0 and 1, for indexing purposes). We will display their names to them on the screen, but in the background, we will keep track of them based on their number. This function should take 1 argument, an integer (either 0 or 1) representing the player and should return the opposite integer (1 if 0 is entered and 0 if 1 is entered). This is a simple function, but it will make our code cleaner later. Use your constants! Using Thonny
