I created a command line game in python for an online course; a course requirement is to write a technical blog post, so here goes!
I wrote a simple syntax version of the classic Mexican game Loteria, combining my interest in programming AND Spanish.
Loteria is similar to Bingo. A user selects a game board; each board has 16 classic personas or objects. Ex: el gallo (the rooster).
The shuffled deck of cards contains 54 cards, each with a unique persona (and in classic tradition, each card has a unique Spanish verse). When a card is drawn, if the same persona appears on the board, the user puts a bean on that square. When 4 squares in a row or column have beans, the board is a winner.
OK, so on to python....
My game is a single player game which arranges a board of 16 randomly selected personas, and shuffles the deck of 54 cards.
The board simply displays the titles of the cards in a grid by using print statements.
I created 2 classes of objects for the game.
1- The DrawDeck class, which takes a list as an argument and retains a working copy of a list of lists (representing the cards). Each 'card' in the list is itself a list containing the id, the name, and the verse as elements.
The order of the cards are randomized when the object is created.
DrawDeck has a .draw method, which returns the card in the 0th position, using a .pop method, so the deck gets smaller as each card is drawn.
2- The Board class is where most of the action happens. The Board class takes a list (a deck of cards) as an argument, randomizes the list and loops through the first 16 cards, writing them into a cards on board list.
The .layout method then prints the board as a 4 x 4 grid.
The .mark method takes an argument of a list (card) and loops through the cards on board to see if there is a match. if yes, the card title is updated as BEAN and the id value =1000. Then the .layout is called again to reset the board.
The .calc method takes no arguments and simply includes if and elif evaluations to determine whether there are 4 beans on the board in a row or column, by summing the ids. If the sum of a row or column is 4 * 1000, then it is a winner and a boolean variable called won is set to True.
Game play starts with the user pressing any key, and runs in a loop while won = False. The user is asked to type a key to draw a new card on each turn. The card title and verse are displayed, and the board is redrawn on each turn, with any matching cards showing BEAN.
Eventually, a winning scenario is produced, won = True, and the game tells the user 'You won' and displays the number of turns used and the number of cards remaining in the draw deck.
The game file is game_user_prompt.py at https://github.com/BMSawyer/Loteria
Final note: Because I ran into a known issue where git bash for windows 10 was not accepting & returning the control to the command line for user input when running python, I wrote an alternate version (game.py) where there is no user input required, the game loops through in the same sequence until the winning board is declared. Was able to work around the git bash issue by using winpty.
Vamos a jugar!
