A card with a grid of numbers on it is used to play the popular dice game of bingo. Players check off numbers on their cards when they are selected at random by a caller, competing to be the first to mark off all of their numbers in a particular order. We’ll examine how to utilise Python to create a simple bingo game in this lesson.
The following ideas must be understood in order to design a bingo game:
- Lists: A list is a group of items that can contain any sort of data.
- Random module: In Python, random numbers are produced using the random package.
- Loops: Loops are used to repeatedly run a block of code until a predetermined condition is satisfied.
- Functions: A set of statements that carry out a particular activity are grouped together into functions.
Steps:
- Make a list of all potential bingo numbers (1–25).
- For a random order of the numbers, mix up the list.
- With the centre square denoted as “free,” make a bingo card with a 5×5 grid of numbers.
- Make a list of 24 distinct bingo cards with various number combinations.
- Write a function that draws a number at random from the shuffled list of bingo numbers and checks to see whether any of the numbers on the players’ bingo cards match the selected number.
- When a player has checked off all the numbers in a certain sequence, keep drawing numbers (e.g., a straight line, a diagonal, or all four corners).
