Python Fiddle gives you a rich Python environment in your browser with the scientific stack ready to go — perfect for quick analysis, prototyping, and sharing results with colleagues.
No conda environment to create, no package conflicts to resolve. Open the browser and start analysing.
pandas, numpy, matplotlib, scipy, scikit-learn, seaborn, statsmodels — all available out of the box.
Share a link instead of an .ipynb file. Colleagues can view and run your notebook without any setup.
Load local CSV, JSON, or other data files directly into your browser session for analysis.
Charts from matplotlib, seaborn, plotly, altair, and bokeh render inline — just like a local Jupyter notebook.
See Matplotlib Example →Let the AI assistant write and explain analysis code, suggest visualisations, and help interpret results.
Try AI Data Analyst →Load local CSV, Excel, or JSON files directly into your browser session — no need to host your data anywhere before you can start analysing it.
Mix code, markdown, and output in a single document — the same notebook-style workflow you know from Jupyter.
Open a Notebook →Powered by Pyodide, the full scientific Python stack runs directly in your browser — no installation, no dependency conflicts.
Send a link instead of a notebook file. Colleagues can view your analysis, run the code, and fork their own copy — no Jupyter installation required on their end.
Share your analysis as a link — no .ipynb attachments
Works alongside Jupyter — use Python Fiddle for quick exploration and sharing
Open the notebook and start analysing — pandas, matplotlib, and the rest are already loaded.
