Solving Import Issues in Python: Making Your Script Work with pytest and Regular Execution

When it comes to Python programming, one common challenge many developers face is making their scripts work seamlessly both during normal executions and when running tests with pytest. This dilemma often arises due to import issues that stem from the structure of your project. In this guide, we'll delve into a typical scenario where one developer encountered such a problem and how they efficiently resolved it.

This error can stem from several factors, primarily how Python looks for modules based on your current working directory and the way files are organized.

The Solution

To tackle the issue while keeping your imports intact, here’s a straightforward solution:

Step 1: Remove __init__.py Files

The first step is to remove the __init__.py files from both the src/ and tests/ directories. While these files are traditionally used to mark directories as Python packages, their presence can complicate import paths in this case.

With this change, your updated file structure will look like this:
