Resolving PermissionError When Storing Game Data in Python

As a budding game developer, you might face various challenges while coding your game, especially when it comes to file handling. One common issue is the dreaded PermissionError that can occur when your program attempts to read from or write to a file. If you've found yourself in a situation where your game runs perfectly fine before installation but throws a PermissionError: [Errno 13] Permission denied after installation, you're in the right place. In this post, we'll take a closer look at how to fix this issue and ensure that your game saves player scores without any hassles.

Understanding the Issue

Incorrect File Path: If you do not specify an absolute path, Python defaults to the current working directory, which may require administrative privileges to access.

File Already Exists: If the file was created by another user or process, your current user may not have permission to modify it.

Solution: Change the File Storage Location

To circumvent this issue, a recommended approach is to store your data within the user's home directory. This will typically allow read and write access without requiring additional permissions. Here's how to implement this solution in your game's score storage function.

Step-by-Step Code Implementation

Import the os Module: This module gives you access to functions for interacting with the operating system.

Conclusion

By redirecting your game's file output to the user’s home directory, you can avoid common permission issues that arise when storing player data. This approach not only enhances the user experience by preventing errors but also keeps your code clean and efficient.

Take the time to adjust your file handling strategies as you develop your games, and you'll save yourself from unnecessary frustration. Happy coding, and may your game save the highest scores without a hitch!
