PyScript lets you run Python scripts right in the browser, side by side with JavaScript, with two-way interaction between your code and the web page.

PyScript has no server component; everything runs directly in the browser. Using PyScript, useful components from both the Python and JavaScript worlds can be deployed side-by-side.

Playwright, a Python library, allows developers to essentially control the browser with a few lines of Python code to automate cross-browser testing for single-page web apps and Progressive Web Apps.
