Hangman step 2

range(len(word)) : if length was 5 , 0,1,2,3,4
range(1, 3) : 1,2 -> not including 3

TODO-2: I made an empty list 'display =[ ]' repeatedly to fill in the data using '+=' to add the new letters, however, angela simply exchanged word only when it meets the condition. She used 'display[position] = letter' to exchange the letter.

#Step 2

import random
word_list = ["aardvark", "baboon", "camel"]
chosen_word = random.choice(word_list)

#Testing code
print(f'Pssst, the solution is {chosen_word}.')

#TODO-1: - Create an empty List called display.
#For each letter in the chosen_word, add a "_" to 'display'.
#So if the chosen_word was "apple", display should be ["_", "_", "_", "_", "_"] with 5 "_" representing each letter to guess.

guess = input("Guess a letter: ").lower()

display = []
for letter in chosen_word:
  display += "_"

print(display)

#TODO-2: - Loop through each position in the chosen_word;
#If the letter at that position matches 'guess' then reveal that letter in the display at that position.
#e.g. If the user guessed "p" and the chosen word was "apple", then display should be ["_", "p", "p", "_", "_"].

#<my code>
display = []
for i in range(len(chosen_word)):
  if chosen_word[i] == guess:
    display += chosen_word[i]
  else:
    display += "_"
    
#<Angela's code>  
word_length = len(chosen_word)
for position in range(word_length):
    letter = chosen_word[position]
    if letter == guess:
        display[position] = letter


#TODO-3: - Print 'display' and you should see the guessed letter in the correct position and every other letter replace with "_".
#Hint - Don't worry about getting the user to guess the next letter. We'll tackle that in step 3.
print(display)

Hangman step3

• Logic was confusing. Angela's code used one more variable called "end_of_game" on top of 'not in' logic for readability.
• Indentation was extra important. At first, print part was skipped in my code because I didn't indent it.
• "while not False" means "While True" it goes into infinite loop, without the line (if "_" not in display:) underneath, it won't end.

#Step 3

import random
word_list = ["aardvark", "baboon", "camel"]
chosen_word = random.choice(word_list)
word_length = len(chosen_word)

#Testing code
print(f'Pssst, the solution is {chosen_word}.')

#Create blanks
display = []
for _ in range(word_length):
    display += "_"

#TODO-1: - Use a while loop to let the user guess again. The loop should only stop once the user has guessed all the letters in the chosen_word and 'display' has no more blanks ("_"). Then you can tell the user they've won.

#<my code>
while '_' in display:

  guess = input("Guess a letter: ").lower()

#Check guessed letter
  for position in range(word_length):
    letter = chosen_word[position]
    if letter == guess:
        display[position] = letter

    print(display)

  if not '_' in display:
    print("win")


#<angela's code>
end_of_game = False

while not end_of_game:

  guess = input("Guess a letter: ").lower()

#Check guessed letter
  for position in range(word_length):
    letter = chosen_word[position]
   
    if letter == guess:
        display[position] = letter
    print(display)

  if "_" not in display:
    end_of_game = True
    print("you win.")

Hangman step 4

Multiple ifs, indentation was very confusing. I first wrote 'else:' under the for loop of #TODO2 and it didn't work. I had to try different code a few times.

        if letter == guess:
            display[position] = letter

    #TODO-2: - If guess is not a letter in the chosen_word,
    #Then reduce 'lives' by 1. 
    #If lives goes down to 0 then the game should stop and it should print "You lose."
    
    if guess not in chosen_word:
      lives -= 1
     
      if lives == 0:
        end_of_game = True
        print("You lose.")
        
    #Join all the elements in the list and turn it into a String.
    print(f"{' '.join(display)}")

    #Check if user has got all letters.
    
    if "_" not in display:
        end_of_game = True
        print("You win.")

    #TODO-3: - print the ASCII art from 'stages' that corresponds to the current number of 'lives' the user has remaining.
    
    print(stages[lives]) 

Hangman stage 5

It's important to add full functionality in the end after getting everything right. In this case, importing Ascii (design), word_list from different files and improving user experience by gently nudging them with hints.

• Module:
  from hangman_art import logo, stages - > you can import multiple things in one line, at once.
