Python
Modulenotfounderror When Importing Your Functions

To create a module in Python and properly import functions from a utils folder, you need to ensure that Python can find the utils package. Here’s a step-by-step guide to help you resolve the ModuleNotFoundError and structure your project correctly:

1. Directory Structure

First, ensure your directory structure looks like this:

project/

├── utils/
│   ├── __init__.py
│   └── get_env.py

└── scripts/
    └── list_droplets.py
  • __init__.py is necessary to mark the utils directory as a package.

2. Content of __init__.py

You can leave __init__.py empty or use it to initialize the package. Its presence allows you to import modules from the utils directory.

3. Setting Up the PYTHONPATH

To ensure Python can find the utils package, you might need to set up the PYTHONPATH environment variable. Here’s how to do it:

Temporary Solution (for current session)

In your terminal or command line, you can temporarily set the PYTHONPATH:

For Unix-like systems (Linux/macOS):

export PYTHONPATH=/path/to/project

For Windows:

set PYTHONPATH=C:\path\to\project

Replace /path/to/project or C:\path\to\project with the actual path to your project directory.

Permanent Solution (add to profile script)

To make this change permanent, you can add the export PYTHONPATH=... line to your shell profile script (.bashrc, .zshrc, etc.) or set it in your system environment variables on Windows.

4. Importing the Function

In your list_droplets.py script, you should be able to import functions from the utils package like this:

from utils.get_env import get_do_token

5. Running the Script

Make sure you run your script from the project directory or ensure that PYTHONPATH is correctly set.

python scripts/list_droplets.py

6. Troubleshooting

  • Ensure __init__.py exists: Python requires this file to recognize a directory as a package.
  • Check the PYTHONPATH: Ensure it's correctly pointing to the project directory.
  • Verify file paths: Double-check the file names and paths to ensure they match the import statements.

By following these steps, you should be able to create a module in Python and import functions from your utils folder without encountering the ModuleNotFoundError.
