Relative Imports in Python 3: Troubleshooting ModuleNotFoundError

In Python 3, relative imports allow you to import modules within the same package. However, when encountering the error "ModuleNotFoundError: No module named 'x'", understanding the difference between relative and absolute imports is crucial.

Absolute Imports

Absolute imports locate modules on the sys.path, the list of directories Python searches for modules. To perform an absolute import, use the following syntax:

<code class="python">import module</code>

In your example, absolute importing config.py would look like this:

<code class="python">import config</code>

Relative Imports

Relative imports import modules relative to the current module's location within a package. To perform a relative import, use the following syntax:

<code class="python">from . import module</code>

However, relative imports require the module to be within a package. If test.py is not in a package, a relative import will not work.

Troubleshooting

Based on the provided code, the issue is that test.py is attempting to perform a relative import when it is not part of a package. The error message "ImportError: cannot import name 'config'" indicates that the config module cannot be found in the relative path.

Solution

To resolve this issue, you can make test.py part of a package by adding an __init__.py file to the same directory as test.py. Alternatively, you can use absolute import as follows:

<code class="python">import config</code>

This will look for config.py in the sys.path, ensuring that the import works as intended.
