API: Python Terminal (r1)

This API supports Python in the browser. The World is pure Python (no JavaScript).

PyScript with fast compiler and Terminal:

• The API includes PyScript release 2025.8.1.
• This compiles Python using the fast MicroPython compiler.
• This API creates a Pyscript Terminal for input and output.

This API works as follows:

• The code is pure Python.
• At run-time the Python code is interpreted by PyScript and run.
• The Python code is syntax highlighted. It is not syntax checked. We do not have Python syntax checking yet.
• You can use await input() to read input from the user.
• print() outputs to the Terminal.

For help on how to use Python in the Pyscript environment, see:

• PyScript docs.

This API has further features:

• Obfuscation is disabled. We do not have Python obfuscation yet.
• Includes jQuery 3.6.0.
• The API sets a blank page and sets a page title.
• There is no run header.
• You reload and close the page like any other tab.
• The API loads up minimal CSS that should not conflict with user CSS.
• The style of the blank page is a body with margin 0 and padding 0. You can change it using JS like this:

   
    $('body').css( "margin", "20px" );
    $('body').css( "padding", "20px" );
  

Screenshots:

• The screenshot does not assume there is a canvas. Instead it takes a screenshot of the HTML.
• It uses the html2canvas library to build a screenshot of your page using JS.
• The html2canvas library has some limitations and may not be able to accurately screenshot your page.

The underlying file type is .js:

• The basic design of this site is for .js files. And there are issues with .py files on the server. So we simply leave the underlying file type as .js, which is safe. So even though there is no JS code and it is pure Python, underneath the file type is .js. It does not matter and you will not normally notice.
