| 2 | +Exercise 31: Guess Letters |
| 3 | +This exercise is Part 2 of 3 of the Hangman exercise series. |
| 4 | +The other exercises are: Part 1 and Part 3. |
| 5 | + |
| 6 | +Letβs continue building Hangman. In the game of Hangman, a |
| 7 | +clue word is given by the program that the player has to |
| 8 | +guess, letter by letter. The player guesses one letter at a |
| 9 | +time until the entire word has been guessed. (In the actual |
| 10 | +game, the player can only guess 6 letters incorrectly before |
| 11 | +losing). |
| 12 | + |
| 13 | +Letβs say the word the player has to guess is "EVAPORATE". |
| 14 | +For this exercise, write the logic that asks a player to guess |
| 15 | +a letter and displays letters in the clue word that were |
| 16 | +guessed correctly. For now, let the player guess an infinite |
| 17 | +number of times until they get the entire word. As a bonus, |
| 18 | +keep track of the letters the player guessed and display a |
| 19 | +different message if the player tries to guess that letter |
| 20 | +again. Remember to stop the game when all the letters have |
| 21 | +been guessed correctly! Donβt worry about choosing a word |
| 22 | +randomly or keeping track of the number of guesses the player |
| 23 | +has remaining - we will deal with those in a future exercise. |
| 24 | + |
| 25 | +An example interaction can look like this: |
| 26 | + |
| 27 | +>>> Welcome to Hangman! |
| 28 | +_ _ _ _ _ _ _ _ _ |
| 29 | +>>> Guess your letter: S |
| 30 | +Incorrect! |
| 31 | +>>> Guess your letter: E |
| 32 | +E _ _ _ _ _ _ _ E |
| 33 | +... |
| 34 | +And so on, until the player gets the word. |
