Learn PYSCRIPT with Real Code Examples
Updated Nov 26, 2025
Practical Examples
Print 'Hello World' in a webpage using Python
Manipulate text content of an HTML element
Plot a Matplotlib chart directly in the browser
Create interactive buttons and form inputs using Python
Load CSV data and display results dynamically
Troubleshooting
Ensure browser supports WebAssembly
Check PyScript version and CDN links
Verify package names in `py-env`
Use browser console for Python runtime errors
Avoid blocking operations; use async for heavy tasks
Testing Guide
Run HTML page in browser to test PyScript code
Check console logs for errors
Verify package imports from `py-env`
Test DOM interactions and widgets
Iterate and modify Python scripts for correctness
Deployment Options
Static web hosting (GitHub Pages, Netlify, Vercel)
Interactive demos for education
Prototyping Python web apps
Embedding Python visualizations in blogs or docs
Client-side applications without backend
Tools Ecosystem
PyScript runtime (JS + WASM)
Pyodide Python interpreter
HTML/CSS for web page structure
Popular Python libraries (NumPy, Pandas, Matplotlib)
Browser developer console for debugging
Integrations
