Was business logic separated into a separate module or plugin, similar to Django architectural approaches?

In Django architecture, business logic is often separated into distinct modules or applications, which helps to better structure the code and facilitate maintenance. Similarly, in Python projects, it is recommended to separate business logic from presentation and data access, for example, by isolating it into separate modules, classes, or plugins.

Example: if you have a web application, the data processing logic and rules can be placed in a separate module services.py or package business_logic, and in controllers (views), only these functions or classes are called. This improves code readability and testability.
