3. Th e game currently displays the instructions once, at the beginning. Modify the game to remove the automatic display of its instructions and instead allow players to display the instructions as a hidden cheat, accessible when the h key is pressed. Make it so the existence of this feature is revealed when the player is rst prompted to play the game, as well as when the player is prompted to continue playing after a round of play.

4. Th e game currently prevents the player from guessing the same letter twice, acting on the assumption that the player remembers any previous guesses. To provide better feedback, modify the game so that it displays a list of all the wrong guesses each time the player enters a guess thats already been tried. Hint: Use the inspect method to display the contents of the list array. Also, use a regular expression to remove the double quotation marks that are included when array contents are displayed.

5. Whenever play ends without the player having guessed the secret word, the game displays the secret word in all uppercase characters. Modify the game so that only the rst letter of the word is uppercase. You could implement this change by retyping each of the game words stored in the list array, of course. Instead, convert all the words to lowercase, and then, using a regular expression, change the rst character of the game word to uppercase.
