Best Practices for Streamlit Apps

When building Streamlit apps, following a few best practices will help you write code that is easier to maintain, extend, and share. Here are some key guidelines to keep in mind:

• Use functions to organize your code and separate concerns;
• Manage widget state carefully to ensure consistent app behavior;
• Keep your code readable with clear variable names, comments, and logical structure.

By structuring the app with dedicated functions for loading data, plotting, handling the sidebar, and running the main logic, you make your code much easier to read, test, and reuse. Each function has a clear responsibility, so you can quickly update or extend parts of your app without affecting unrelated sections. This modular approach also encourages cleaner code and makes collaboration with others more straightforward.
