Shiny for Python is a framework for developing interactive web applications, dashboards, and data exploration tools. It enables developers to connect user interface controls with calculations, visualizations, and other application outputs without manually managing every interaction.
The framework uses reactive programming to automatically update dependent outputs when inputs or underlying data change. This approach is particularly useful for applications involving statistical analysis, scientific computing, and interactive data exploration.
Shiny for Python offers two development styles. Express provides a concise approach for building applications, while Core offers more explicit control over interface structure, application logic, and reactive behaviour.
Applications can range from simple interactive visualizations to more elaborate tools with multiple views and reusable components.
This is free and open source software.
Key Features
- Reactive programming system automatically updates dependent calculations and outputs.
- Express and Core programming styles for different application development needs.
- Rich collection of inputs including sliders, selectors, checkboxes, date controls, and file uploads.
- Interactive tables, data grids, charts, and graphical outputs.
- Support for Matplotlib, Plotly, and other visualization libraries.
- Flexible page layouts with navigation panels, sidebars, cards, and responsive columns.
- Reusable application modules for organizing complex interfaces.
- Reactive calculations and effects with automatic dependency tracking.
- Asynchronous programming support for handling concurrent operations.
- Dynamic interface generation based on application state and user input.
- Support for interactive data filtering, selection, and exploration.
- Customizable appearance through themes, CSS, and HTML components.
- Session management for handling multiple simultaneous users.
- Bookmarking support for preserving and restoring application state.
- Integration with the wider Python data analysis ecosystem.
- Cross-platform support – runs on Linux, macOS, and Windows.
