hangman

Milestone 1

• This is a basic python program that performs two functions
• The first function returns a random word from a list of fruits provided using the random.choice method

word_list = ["Apple", "Pear", "Orange", "Grapes", "Guava"]
    word = random.choice(word_list)
    print(word)

• The second function gets an input from the user and saves the input in a variable called "guess"
• checks if the length ia equal to 1 and if the user is an alphabet
• And prints out an output based on the values the user inputs

guess = input("Enter a single letter here:")
if len(guess) == 1 and guess.isalpha():
    print("Good guess")
else:
    print("Ooops, That's not a valid input")

Milestone 2

• This second milestone of the game adds 2 functionalities to it
• The first fuction converts the user's guess to lowercase with thw lower() and checks if the guess is in the word variable from milestone 1

def check_guess(guess):
    guess = guess.lower()
    if guess in word:
        print(f'Good guess. {guess} is in the word')
    else:
        print(f'Sorry, {guess} is not in the word.Try again')

• The second function checks that the user has provided a single alphabet character and breaks the while loop that iteratively asks for a valid input
• the first function is then called within this function but outside the while loop

def ask_for_input():
    while True:
        guess = input("Enter an alphabet: ")

        if len(guess) == 1 and guess.isalpha():
            break
        else:
            print("Invalid letter. Please enter a single alphabetic character")
            
    check_guess(guess)

Milestone 3

• In this milestone the Hangman class was created and was initialised with two parameters(word_list, num_lives) within the init constructor
• Four other class variables self(word, word_guessed, num_lives, lIst_of_guesses) were defined within the constructor method

class Hangman:
  def __init__(self, word_list, num_lives=5):
      
      self.num_lives = num_lives
      self.word_list = word_list

      self.word = random.choice(word_list)
      self.word_guessed = list(len(self.word)*",")
      self.num_letters = len(set(self.word) - set(self.word_guessed))
      self.list_of_guesses = []

• The second method check_guess allows for the verification of the letter provided by the user,
• First it checks if the guess is in the word variable, if this condition is met, it appends the letter into the list of word_guessed indexing it at a particular position
• if this conditions are not met the else block of the code runs

def check_guess(self, guess):
      self.guess = guess.lower()
      if self.guess in self.word:
          print(f"Good guess! {guess} is in word")
          for i, letter in enumerate(self.word):
              if letter == self.guess:
                  self.word_guessed[i] = self.guess
          self.num_letters -= 1
      else:
          self.num_lives -= 1
          print(f'Sorry {letter} is not in the word')
          print(f'You have {self.num_lives} left')
      self.list_of_guesses.append(guess)

• The last method ask_for_input() gets the input from the user and checks for two conditions within the while loop

1. if the length of the guess is 1
2. if the guess is an alphabet

 def ask_for_input(self):
       while True:
           guess = input("Enter a letter: ")
           if len(guess) != 1 and guess.isalpha() == False:
               print("Invalid letter. Please enter a single alphabetic character")
           elif guess in self.list_of_guesses:
               print("You already tried that letter!")
           else:
               self.check_guess(guess)
               self.list_of_guesses.append(guess)

Milestone_4

• Having defined all the methods within the Hangman class that would be required to play the game, this milestone defines a fuction play_game outside the class
• Within this play_game function, an instance of the Hangman class "game" is created that takes in two parameters (word_list, num_lives)
• A while loop is also created that checks for the change in state of certain attributes of the class to print a result of the game
• The play_game function is finally called outside the while loop

def play_game():
    game = Hangman(word_list=["apple", "guava", "pear", "berry", "grape"], num_lives=10)
    while True:
        if game.num_lives == 0:
            print("You Lost! {game.word_guessed} is the correct word")
            break
        elif game.num_lives > 0 and game.num_letters <= 0:
            print("Congratulations! You won the game")
            break
        elif game.num_letters > 0:
            game.ask_for_input()
