How to Fix the None Output in Your Python Scissor Paper Rock Game

Are you working on a Scissor Paper Rock game using Python but facing an issue with it printing None at the end? This is a common problem that many beginners encounter when they don't fully understand how functions in Python work. In this guide, we will explore the root cause of the issue and provide you with a clear solution to fix it.

Understanding the Problem

When you run your game, you might see output that looks something like this:

The None appears at the end of your output, and it can be confusing. So, let’s break down why this is happening.

What Causes the None Output?

The core of the issue lies in the game() function you have defined. Here's a simplified explanation of what's going wrong:

The game() function is designed to print the game's result (like "YOU WIN" or "sorry man you lost"). However, it does not have a return statement. In Python, when a function does not return a value explicitly, it will return None by default.

When you call x = game(user, comp) and then print(x), you are trying to print the return value of the function, which is None.

How to Fix the Issue

To eliminate the None from your output, you need to modify your game function so that it returns a value instead of just printing directly. Follow these steps:

Step 1: Modify the game() Function

Instead of using print statements within the game() function, you should return the result. Here’s how you could adjust it:

Step 2: Update the Print Statement

With the new structure, you’ll print the result after calling the function:

Conclusion

By applying these alterations, your Python Scissor Paper Rock game will no longer output None. Instead, it will cleanly display the results of the game based on the player and computer choices without any confusion.

Happy coding and enjoy your game!
