📺 Video Tutorial¶
Let’s code a HANGMAN GAME in Python! 🕺 (21:13)
What You’ll Learn¶
In this chapter, you’ll build a complete Hangman word-guessing game that demonstrates dictionaries for ASCII art storage, sets for efficient letter tracking, list manipulation for hint displays, random word selection, and game loop design. You’ll create an engaging game with visual feedback, input validation, win/loss conditions, and professional game state management.
Learning Objectives¶
Use dictionaries to store and retrieve ASCII art based on game state
Implement sets for fast letter lookup and duplicate prevention
Manipulate lists to reveal guessed letters in word hints
Validate user input with
isalpha()and length checkingDesign game loops with proper win and loss conditions
Use
enumerate()for simultaneous index and value iteration
Concept Explanation¶
Game Mechanics¶
Hangman game flow:
Start → Pick random word → Show blanks → Get guess →
Check if correct → Update display → Check win/loss → Repeat
Win Condition: Guess all letters before running out of attempts
Loss Condition: 6 wrong guesses (complete hangman)
Dictionary for ASCII Art¶
Store different hangman states in a dictionary:
hangman_art = {
0: """
-----
| |
|
=========
""",
1: """
-----
| |
O |
=========
""",
# ... more states ...
6: """
-----
| |
O |
/|\\ |
/ \\ |
=========
"""
}
# Access art by wrong guess count
print(hangman_art[3]) # Show state for 3 wrong guesses
Set Data Structure¶
Sets provide O(1) lookup speed and prevent duplicates:
guessed_letters = set()
# Add letter
guessed_letters.add('a')
guessed_letters.add('b')
guessed_letters.add('a') # Duplicate - ignored
print(guessed_letters) # {'a', 'b'} - no duplicates
# Fast membership checking
if 'a' in guessed_letters: # O(1) - instant lookup
print("Already guessed")
Set vs List for this purpose:
# List - slow lookup, allows duplicates
letters_list = ['a', 'b', 'c']
'a' in letters_list # O(n) - checks each element
# Set - fast lookup, no duplicates
letters_set = {'a', 'b', 'c'}
'a' in letters_set # O(1) - instant hash lookup
List Multiplication for Hints¶
Create hint list with underscores:
answer = "python"
hint = ["_"] * len(answer)
# Result: ['_', '_', '_', '_', '_', '_']
# Alternative (manual):
hint = []
for letter in answer:
hint.append("_")
Enumerate for Index and Value¶
Get both index and value when iterating:
answer = "cat"
guess = 'a'
# Without enumerate - need counter
i = 0
for letter in answer:
if letter == guess:
hint[i] = guess
i += 1
# With enumerate - cleaner
for i, letter in enumerate(answer):
if letter == guess:
hint[i] = guess
Enumerate examples:
for i, letter in enumerate("python"):
print(f"Index {i}: {letter}")
# Output:
# Index 0: p
# Index 1: y
# Index 2: t
# Index 3: h
# Index 4: o
# Index 5: n
Input Validation¶
Multiple validation checks:
guess = input("Enter letter: ").lower()
# Check 1: Must be alphabetic
if not guess.isalpha():
print("Letters only!")
continue
# Check 2: Must be single character
if len(guess) != 1:
print("Single letter only!")
continue
# Check 3: Not already guessed
if guess in guessed_letters:
print("Already guessed!")
continue
String Methods for Validation¶
"a".isalpha() # True
"5".isalpha() # False
"ab".isalpha() # True
"a5".isalpha() # False
len("a") == 1 # True
len("ab") == 1 # False
Examples¶

Common Mistakes to Avoid¶
Mistake 1: Not Using Set for Guessed Letters¶
❌ Wrong:
guessed_letters = [] # List - slow lookups
if letter in guessed_letters: # O(n) complexity
print("Already guessed")
✅ Correct:
guessed_letters = set() # Set - fast lookups
if letter in guessed_letters: # O(1) complexity
print("Already guessed")
Mistake 2: Modifying String Instead of List¶
❌ Wrong:
hint = "______"
# hint[0] = 'a' # Error! Strings are immutable
✅ Correct:
hint = ["_"] * 6
hint[0] = 'a' # Works! Lists are mutable
Mistake 3: Not Checking All Occurrences¶
❌ Wrong:
if guess in answer:
index = answer.index(guess) # Only finds first!
hint[index] = guess
✅ Correct:
if guess in answer:
for i, letter in enumerate(answer): # Check all positions
if letter == guess:
hint[i] = guess
Mistake 4: Wrong Win Condition¶
❌ Wrong:
if len(guessed_letters) == len(answer): # Wrong!
print("You win")
✅ Correct:
if "_" not in hint: # All letters revealed
print("You win")
