Organize a large Streamlit project by separating UI components and logic into distinct directories. Create 'app_pages/' for UI modules and 'utils/' for utility functions to ensure modularity and maintainability as the codebase grows.

Separating UI code from logic in Streamlit applications improves code quality, readability, and maintenance. By isolating UI components from utility functions, developers can manage complexity and scale multi-page apps without degrading performance or clarity.

The best way to structure a Python Streamlit app for maintainability is using a modular architecture. Split your codebase into separate UI and utility modules, minimizing main-guard usage to keep functions efficient and the application scalable.

Start modularizing your Streamlit codebase by creating 'app_pages/' and 'utils/' directories in your project folder. Define your UI components in the pages directory and implement the underlying logic within the utility modules.

You need to restructure your Streamlit code when the application reaches significant complexity with multiple pages. Adopting a modular structure with separate UI and utility modules at this stage prevents maintainability issues as the project expands.
