Brython: Run Python in Browser

Brython is an implementation of Python 3 running in the browser. It allows you to execute Python code in an HTML page without needing any plugins. It uses the browser's JavaScript engine to run the Python code.

What is Brython?

Brython is an open-source implementation of the Python programming language that is designed to run in a web browser. It allows developers to write Python code that executes directly in the browser, instead of running on the server.

Some key things to know about Brython:

  • It implements Python 3 syntax and features, so any valid Python code should run properly.
  • It uses the browser's JavaScript engine to execute the Python code, so no plugins or compilers are needed.
  • The Python code runs in the browser, so it can easily interact with the DOM and other web APIs.
  • Brython can be used for client-side scripting and to create rich, responsive web apps entirely in Python, no JavaScript required.
  • It can access and manipulate CSS styles, create graphics/animations, handle browser events, communicate via AJAX, store data locally, and more.
  • Brython supports popular Python libraries like NumPy, Pandas, Matplotlib, and more to allow complex data processing and visualization.

In summary, Brython brings the power and simplicity of Python to front-end web development, removing the need to switch between languages for client vs server programming.
