Master For and While Loops in Python to Create a Hangman Game

Create your own Hangman Game in Python

You will learn how to loop over a Python list. Further, you will learn the power of a While loop. Finally, you will create a Hangman Game.

Step 1: Loop over a list or sequence

Looping over a list can be done as follows (see more about lists here).

my_list = ['First', 'Second', 'Third']
for item in my_list:
    print(item)

This can also be done over a string, which is a sequence.

s = "Rune"
for c in s:
    print(c)
    print("Inside loop")
print("Outside the loop")

Where we notice the syntax of how the indentation works. What is inside and outside the loop?

Step 2: While loops and how they differ

Notice that for-loops in Python loop over a predetermined length. In the above cases, the length of the list or the length of the string.

If you want a loop that is dependent on something inside the loop.

What do I mean? Let’s take an example.

value = 10
while value > 0:
    value = int(input("Value? "))

As you see – this loop is dependent on input in the loop. If you type zero or a negative value, it will stop.

Step 3: Description of the Hangman Game

A description of the Hangman Game (see wiki for further details)

  • The game is as follows.
  • Computer has a list of words.
  • Computer chooses a random word from the list.
  • The player gets 10 wrong guesses (10 turns).
  • The game follows this loop
    • Computer prints the word character by character replacing with underscore those not guessed yet (initially no characters have been guessed).
    • Player guesses a character.
    • If a character is not in words, a turn is withdrawn
    • If no one turns left, the computer wins.
    • If Player has guessed all characters, Player wins

Step 4: Implementing the Hangman Game

Let’s try to implement the Hangman Game

import random
words = ['father', 'enterprise', 'science', 'programming', 'resistance', 'fiction', 'condition', 'reverse', 'computer', 'python']
word = random.choice(words)
turns = 10
guesses = ''
while turns > 0:
    print(f"Turns left: {turns}")
    
    guessed_all = True
    for c in word:
        if c in guesses:
            print(c, end=' ')
        else:
            print('_', end=' ')
            guessed_all = False
    print()
    if guessed_all:
        print("You won")
        break
    
    guess = input("Guess a character: ")
    
    if guess in word:
        guesses += guess
    else:
        turns -= 1
else:
    print("You lost")
