Why is my import from utils.py resulting in ModuleNotFoundError?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I have a simple Django project where I am trying to import a function from one Python file into another. Both files, utils.py and views.py, are located in the same directory of my application. However, when I run my code, I get a ModuleNotFoundError.

In utils.py I have defined the following function:

PYTHON
def greet(name):
    print('Hello ' + name)

In views.py I am using this import statement:

PYTHON
from utils import greet

Later in views.py, I try to call the function within a Django view:

PYTHON
@login_required(login_url='login')
def connect_to_dropbox(request):
    greet('Hello!')

When executing the application, I see the following error message:

BASH
File "C:\Users\bob\Documents\Python-Django\Ursus\DropboxUI\views.py", line 3, in <module>
   from utils import greet
ModuleNotFoundError: No module named 'utils'

I use PyCharm as my IDE, and it does not indicate any syntax error. What could be causing this issue with the import?

Django Import Error: ModuleNotFoundError

The issue you're experiencing is related to how Python imports work within a Django project structure. Even though both files are in the same directory, Django's import system requires you to be more specific about the module path.

Solution

In your views.py file, you should modify your import statement to include the app name:

PYTHON
from .utils import greet

The dot (.) before utils indicates that you're importing from the same directory. This is called a relative import.

Alternatively, you can use an absolute import by specifying the full path to the module:

PYTHON
from DropboxUI.utils import greet

Where DropboxUI appears to be your app name based on the error message.

Why This Happens

In Django projects:

When you run the application, Python's import system looks for modules in the Python path
Without the dot prefix or full app name, Python tries to find a module named utils in the installed packages rather than in your local directory
PyCharm might not show errors because it can sometimes resolve imports differently than the Python interpreter at runtime

Additional Tips

Make sure your app is properly registered in INSTALLED_APPS in your settings.py file
If you have complex imports, consider using absolute imports for clarity
Ensure your app directory has an __init__.py file to mark it as a Python package

The relative import (.utils) is generally the preferred approach for importing from the same directory in Django applications.
