Frequently Asked Questions About Online Python IDE
Do I need to install Python or Node.js?
No. TSide uses Pyodide WebAssembly compiled CPython runtime directly in your browser. All scripts execute locally with zero installation required.
Can I render Matplotlib graphs?
Yes. TSide includes built-in vector plot rendering. When your Python script calls plt.show(), charts render directly in an interactive visualization tab with PNG and SVG export.
