Collection of simple games written in Python for practice and reference.

Available Games

Guess the number

A number is randomly generated between 1 and 9. The user must guess it. Key methods / libraries used:

• random.randint()
• is.digit() (boolean) to verify that user has entered a valid number

Rock, paper, scissors

The user plays rock-paper-scissors against the computer. Key techniques:

• random.choice(list) where list contains the possible moves (rock, paper, scissors)
• dictionnary that define the key-value of winning pairs (rock-scissors, paper-rock, scissors-paper)

Hangman Game

The user has to guess a word chosen either by another user or randomly by the program. The game displays correct letters in the proper positions and limits the number of attempts.

Key functions / logic used:

• random.choice(list): selects a random word when playing against the program
• Validation of user-provided words
• Tracking:
  • letters already used
  • correct letters revealed in the word
  • remaining lives
• List manipulation to update the displayed word (['__', '_', ...])
• Input validation (isalpha(), length checks)

Chrono Game

A timing-based game: the program generates a random number of seconds; the user must stop a timer when that time is reached. Key methods:

• time.time() to start and stop the time
• for countdown before the game start:
  • divmod(t, 60) to convert second into minute, second if needed
  • print(timer, '\r') where '\r' allows to print in the same line

Tic-Tac-Toe

Play Tic Tac Toe with the computer, if you have 3 same symboles on a vertical, horizontal or diagonal line, you win ! A simple terminal-based Tic-Tac-Toe game where a human player (X) plays against a computer (O). The game uses OOP (Object-Oriented Programming) and is defined into two main parts: Player classes:

• HumanPlayer asks the user for input
• RandomComputerPlayer picks a random available move

TicTacToe class:

• Manages the board, checks available moves, applies moves, prints the board, and detects wins across rows, columns, and diagonals

The play function runs the game loop, alternates turns between X and O, prints the board after each move, and stops when someone wins or the game ends in a tie.

Snake Game

Simple game where player need to catch element to gain points. The more point you have, the longer your snake will be.
