Structuring Python-Only Kivy Apps

When building Kivy apps, developers can choose between defining the UI using only Python or using kv files. Each method offers its own advantages. Python-only development keeps everything in a single language, which makes debugging easier and allows full use of IDE features like auto completion. It is also better suited for creating dynamic user interfaces that change based on user input or program logic. This approach offers tighter integration between UI and backend code, which is helpful in complex applications.

Kv files provide a clean way to separate layout from logic, which improves code organization and readability. It also includes useful features such as widget ids and automatic property binding, allowing smoother interaction between the interface and the underlying Python code.

In many cases, developers choose to combine both methods. The choice depends on the complexity of the project and developer preference. Both methods are fully supported in Kivy and can be used to create efficient and maintainable applications. However, for professional applications and simple to follow code organisation, Python-only development is strongly preferred.
