What is PythCode? PythCode is a free online Python playground that runs right in your browser. No login. No install. Just open and code. It supports: Numpy, Pandas, Matplotlib and Seaborn out of the box User input() — something many compilers skip Plot Viewer — run your Matplotlib code and view your chart instantly, then export as PNG Shareable links — copy the URL and your code is shared instantly Download as .py — one click saves your file with the right extension Tokyo Night, Dark and White themes — because aesthetics matter FiraCode and 4 other fonts — because devs are picky about fonts (rightfully so) Resizable editor and output panes 👉 Try it here: pythcode.netlify.app The Hardest Part: User Experience I could get the compiler working in a day.
