The Cause of the Issue

The Solution: Using Relative Imports

To resolve this issue and maintain a clean directory structure, you can utilize relative imports. This method allows Python to locate modules based on their position relative to the current script's directory.

Explanation of Relative Imports

The Dot (.): In Python, the single dot represents the current directory. By using from . import view, you're telling Python to look for the view module in the same package or directory as the controller module.

Advantages of Using Relative Imports

Project Organization: You can keep your project structured in multiple directories without issues when importing.

Clarity: Makes it clear where the imported modules are in relation to your current script.

Avoids Clutter: Prevents the need to move files around to get them into the same directory.

Conclusion

If you face any further issues or have additional questions about Python imports, don't hesitate to ask! Happy coding!
