Notebook in the browser - using Pyiodide
Pyodide brings the Python runtime to the browser via WebAssembly, along with the Python scientific stack including NumPy, Pandas, Matplotlib, parts of SciPy, and NetworkX. The packages directory lists over 35 packages which are currently available.
While closely related to the iodide project, a tool for literate scientific computing and communication for the web, Pyodide goes beyond running in a notebook environment. To maximize the flexibility of the modern web, Pyodide may be used standalone in any context where you want to run Python inside a web browser.
