However, if you find that this leads to a ModuleNotFoundError, there’s a very specific fix that you need to implement.

The Solution: Add an __init__.py File

To successfully import local modules within your directory structure, Python requires that you signal to it that a directory contains a package. This is achieved by including a special file called __init__.py. Here’s how you can address the problem:

Step 1: Create the __init__.py File

Navigate to your jobs folder.

Create an empty file named __init__.py. This file can be completely empty; its mere presence is what counts.

Your updated directory should look like this:

Key Takeaways

Presence of __init__.py: Without the __init__.py file, Python treats the directory as a regular folder, not a package.

Conclusion

By understanding the importance of the __init__.py file, you can effectively manage your Python module imports. This small adjustment will streamline your developing experience and resolve the common confusion that arises with local module imports. Don’t hesitate to revisit your project structure, and ensure packages are properly defined.
