Rock Paper Scissors Lizard Spock: Enhancing the Classic Game With Code

Have you ever played Rock Paper Scissors with your friends or family? It’s a classic game that many people have enjoyed for generations.

However, as time has passed, some people have grown weary of the game’s simplicity and have sought to spice things up. That’s where the concept of Rock Paper Scissors Lizard Spock comes in.

In this article, we’ll dive into the code and mechanics behind implementing this variation of the game. We’ll also explore how to use Dictionaries to store the victory relationships for each move, as well as how to update the random number generator function to accommodate the new additions.

Implementing Rock Paper Scissors Lizard Spock

The original game of Rock Paper Scissors has three possible moves that players can make: Rock, Paper, or Scissors. Each move has a specific victory relationship with the other two moves:

– Rock crushes Scissors

– Scissors cut Paper

– Paper covers Rock

Rock Paper Scissors Lizard Spock, on the other hand, adds two new possible moves: Lizard and Spock.

Each move also has specific victory relationships with the others, as follows:

– Rock crushes Scissors and Lizard

– Scissors cut Paper and Lizard

– Paper covers Rock and Spock

– Lizard poisons Spock and eats Paper

– Spock vaporizes Rock and smashes Scissors

Now that we’ve established the new rules of the game, let’s take a look at what it takes to implement it.

Using Dictionaries for Victory Relationships

To keep track of the various victory relationships between each move, we can use Dictionaries. A Dictionary is a built-in Python data type that helps us map keys to values.

In this case, we can use Dictionaries to map each move to a list of moves that it can beat. For example, to store the victory conditions for Rock, we would do the following:

“`python

victory_conditions = {

“rock”: [“scissors”, “lizard”],

“paper”: [“rock”, “spock”],

“scissors”: [“paper”, “lizard”],

“lizard”: [“paper”, “spock”],

“spock”: [“rock”, “scissors”]

}

“`

This code creates a Dictionary called victory_conditions that maps each move to a list of moves that it can beat.

With this set up, we can easily check which moves would beat a given move.

Updating the Code for the New Actions

Now that we’ve established the rules of the game and how we can use Dictionaries to store the victory relationships, let’s take a look at how we can update our code to accommodate the two new moves: Lizard and Spock.

Adding Lizard and Spock to Actions

The first step in updating the code is to add the new moves to the Action list. We can do this with the following code:

“`python

ACTIONS = [“rock”, “paper”, “scissors”, “lizard”, “spock”]

“`

Adding Victory Relationships for Lizard and Spock

Now that we’ve added the new moves to the Action list, we need to add their specific victory relationships to the Dictionary. Using our previous example, here’s how we would add Lizard’s victory conditions:

“`python

victory_conditions[“lizard”] = [“paper”, “spock”]

“`

Similarly, we can add Spock’s victory conditions:

“`python

victory_conditions[“spock”] = [“rock”, “scissors”]

“`

Updating get_computer_selection() Range

Finally, we need to update the get_computer_selection() function to generate a random number between 0 and 4 (inclusive) since we now have five possible actions. Here’s the updated code:

“`python

def get_computer_selection():

return ACTIONS[random.randint(0, 4)]

“`

Now our game is fully compatible with Rock Paper Scissors Lizard Spock, and we can use the Dictionary to determine the winner of each round.

Summary

Rock Paper Scissors Lizard Spock is a fun variation of the classic game that adds two new moves and specific victory conditions for each move. By using Dictionaries to store the victory relationships, we can easily check which moves beat each other.

When updating our code to accommodate the new moves, we simply need to add them to the Action list and update the Dictionary and get_computer_selection() function. With these changes, we can enjoy Rock Paper Scissors Lizard Spock with confidence in the program’s calculations.

In conclusion, by adding Lizard and Spock to the traditional Rock Paper Scissors game, we can enjoy a new level of excitement and unpredictability. With coding modifications, implementing the game of Rock Paper Scissors Lizard Spock can be hassle-free and straightforward.

So try out this new version of the game and enjoy its enhanced complexity!

Code Example: Creating Shorter and More

Manageable Code

The way a code is written can make a huge difference in how easy it is to manage and how efficient it runs. With increasing complexity in applications and software, shorter and manageable code is essential.

In this article, we’ll explore some techniques that programmers can use to create shorter and more manageable code. Additionally, we’ll provide an example of how these techniques can be applied to create shorter and more efficient code.

Shorter Code

One of the most popular techniques for writing shorter code is to use list comprehension. A comprehension is a compact way to create a list, set, or dictionary in one line.

Here’s an example of creating a list of even numbers with list comprehension:

“`python

even_numbers = [x for x in range(10) if x % 2 == 0]

“`

In the above example, we’re generating a list of even numbers from 0 to 10 by using a simple if statement inside the list comprehension. This way, we’re able to write this code in a single line rather than having to write a for loop that accomplishes the same thing.

Another technique for shorter code is using the ternary operator. The ternary operator is a short and concise way to represent an if-else statement.

Here’s an example of how we can use the ternary operator to calculate the absolute value of a number:

“`python

abs_num = num if num >= 0 else -num

“`

In this example, we’re using the ternary operator to calculate the absolute value of the variable num. The statement checks whether num is greater than or equal to 0.

If True, then num is returned as the absolute value. If False, then -num is returned.

Manageable Code

Creating manageable code means breaking down the code into smaller, more manageable units, and organizing them in a logical way. This enables the code to be more efficient, easier to read, and easier to maintain.

One technique for creating manageable code is using functions. Functions break down a complex task into smaller units that are easier to handle.

For example, we can create a function to calculate the area of a rectangle as shown below:

“`python

def calculate_area(length, width):

return length * width

area = calculate_area(7, 10)

“`

In this example, the function calculate_area takes in two arguments (length and width) and returns the area of a rectangle by multiplying these two values. Using the function, the calculation of the area of any rectangle becomes much easier and quicker.

This allows the code to be more efficient and easier to manage. Another technique for creating manageable code is by following the DRY principle (Don’t Repeat Yourself).

This means avoiding repetitive code by creating reusable code snippets, which are often called helper functions. Here’s an example:

“`python

def square(num):

return num ** 2

def cube(num):

return num ** 3

“`

In this example, we’ve created two helper functions to calculate the square and cube of a number.

These functions can be used anywhere in the code to calculate the square or cube of a number. This ensures that the code is concise, efficient, and manageable.

Manageable Code Example

Let’s put these techniques into action and create shorter and more manageable code. Here’s an example that uses these techniques:

“`python

class Student:

def __init__(self, name, age):

self.name = name

self.age = age

self.student_id = 0

def get_student_id(self, id):

self.student_id = id

def display(self):

print(f”Name: {self.name}, Age: {self.age}, ID: {self.student_id}”)

students = []

for i in range(5):

name = input(“Enter student name: “)

age = int(input(“Enter student age: “))

student = Student(name, age)

student.get_student_id(i+1)

students.append(student)

for student in students:

student.display()

“`

In this example, we’ve created a class called Student that takes in the name and age of each student.

Additionally, we’ve created a function called get_student_id that assigns a student ID to each student. Finally, we’ve created a function called display that displays each student’s name, age, and ID.

To make this code shorter and more manageable, we could use list comprehension to reduce the loop code:

“`python

students = [Student(input(“Enter student name: “), int(input(“Enter student age: “))) for _ in range(5)]

for i, student in enumerate(students):

student.get_student_id(i+1)

student.display()

“`

In this implementation, we’ve used list comprehension to create a list of 5 students with their respective names and ages. And in the loop, the get_student_id and display functions are executed for each student.

In summary, these techniques can help both shorten and manage the code. By breaking down a complex task into smaller units and using helper functions, we can create concise and reusable code snippets.

Additionally, by using list comprehension and the ternary operator, we can accomplish more tasks in fewer lines of code. When combined, these techniques help programmers to create more efficient and manageable code.

In conclusion, writing shorter and more manageable code is essential to the success of a program. This can be achieved by using techniques such as list comprehension, ternary operators, functions, and DRY principles.

By breaking down complex tasks into smaller units and organizing them logically, we can create more efficient and readable code. These techniques help to make the code more reusable, maintainable, and manageable overall.

Programmers should consider employing these techniques to improve coding efficiency and ultimately create more useful, user-friendly software. With a focus on concise, efficient, and reusable code, programmers can streamline application development and set themselves apart in the software engineering field.
