What Does the Game of “Rock Paper Scissors” Entail?

Rock paper scissors is a hand game for two players where each person makes one of three hand gestures simultaneously. The gestures are Rock (a closed fist), Paper (an open hand with fingers extended), and Scissors (a fist with the index and middle fingers extended). The game follows a simple rule where Rock beats Scissors, Scissors beats Paper, and Paper beats Rock. In case of a tie, the players continue to play until one of them wins.

“Rock Paper Scissors” is a popular game that is often used to make quick decisions or resolve conflicts in a fun and friendly way. It’s also commonly used in competitive situations, such as tournaments or as a tiebreaker in sports. This article will teach you how to create the game using Python, allowing you to play it on your computer whenever you like. However, it’s important to familiarize yourself with the necessary prerequisites before beginning to ensure the best outcome. Now, let’s dive into the steps involved.

1) Import the “Choice” Method From the “Random” Module

Importing “Choice” from “Random”

In Python, a module is an object that contains attributes with arbitrary names that can be referenced and bound. It’s a file that consists of Python code and can define functions, classes, and variables, as well as include runnable code. The random module has a function called “choice()” that can be used to return a random element from a non-empty sequence. This function is often used to select a random password from a list of words, where the sequence can be a list, string, or tuple.

2) Create a List

A list is stored in the variable “rps.”

Lists in Python are used to store multiple items within a single variable. They are one of the four built-in non-primitive data types in Python that are used to store collections of data. The other three data types are Tuple, Set, and Dictionary, and each of them has different characteristics and uses. To create a list, square brackets [] are used. A list consists of a combination of different elements, which may be repeated at times. This differs from sets, which only contain unique elements. For the program being described, the list will be named “rps”.

3) Create Functions to Define the Computer’s Choices and Random Choices

Functions for “Computer” and “Random Choices.”

In Python, a function is a block of code that only runs when it is called. Parameters, also known as data, can be passed into a function, and a function can return data as a result. To define a function in Python, the keyword “def” is used. To call a function, you simply use its name followed by parentheses. When calling a function, information can be passed into it as arguments, which are specified inside the parentheses after the function name. Any number of arguments can be added, just separated by commas. For the ‘Rock, Paper, Scissors’ game, the parameters ‘select’ and ‘option’ will be used for the “CPU()”: and “ChoiceName()”, respectively.

4) Create a Variable to Store the Computer Function and Define a Function for User Input

Computer Function is stored in the variable “selected”; and a User Input Function is defined.

Variables are used to store data values. Unlike other programming languages, there is no specific command for declaring a variable in Python, as it is created automatically when a value is assigned to it. In the context of the program being described, the reason for saving the computer function to a variable is to make it more efficient to call the “randomChoice()” function once and store the result in a variable, rather than calling it twice. By saving the “CPU()” in a variable, random choices can be prevented for a particular block of code. Additionally, a function called “userInput()” will be created to allow players to enter their choice of option.

5) Write a Code That Includes a While Loop and Handles Incorrect User Input

A while loop that handles incorrect user input.

In Python, there are two main types of loops — the ‘while loop’ and the ‘for loop’. The while loop allows you to run a set of statements repeatedly as long as a certain condition is true. When developing the “Rock, Paper, Scissors” game, it is important to anticipate that users may input incorrect information or characters. To handle this error, you should use a conditional statement “(if/else)”, display the specific error message using the print() function, and then call the userInput() function again to prompt the user to input the correct information.

6) In the While Loop, Create a Code that will Determine When There is a Tie Between the User and the Computer

A conditional statement displaying a tie.

In a game that involves random choices, it is common to have a tie. If the computer and the user make the same random choice, you should display a print statement showing both choices and then indicate that it was a tie. It is important to also call the “userInput()” function again and assign a new value to the computer variable to ensure that the game can continue. This will make it clearer to the user that a tie has occurred and prompt them to continue playing the game.

7) Within the While Loop, Create Conditional Statements that Covers the Six Possible Ways the Game can be Won

Conditional statements show the various ways the game can be won.

The final and crucial step in building the game involves creating a set of conditional statements that will determine the winner. To make the outcome clear to the user, you should first print out the random choices made by both the computer and the user. This will help the user understand how the winner was decided. Once the conditional statements have been written to capture the six possible winning conditions, a break statement should be added to terminate the loop entirely. This will ensure that the game ends once a winner has been determined.
