Python on Pebble. Yes. It works, with a bit of space to write a decent app and some heap memory to spare. AJAX works, as shown in code.

Yup, you can run Python on your Pebble too! Go thank the good folks who
made Transcrypt, a dead-simple way to take your Python code and translate
it to *very* lean Javascript. In our case, instead of browser, we run it
on Pebble using their equally dead-simple Online IDE and Pebble.js library.

Here's a working example, it runs on a real Pebble Classic.

Usage:
    1. Install transcrypt  (You should use a Python virtual environment)
        pip install transcrypt
    2. Python becomes Javascript
        transcrypt pybble.py
    3. Get the (minified) source code
        - on MacOS
            cat __javascript__/pybble.min.js | pbcopy
            OR
            open __javascript__/pybble.min.js
        - On other OSes, copy the content, or optn the file in an editor and do so
            cat __javascript__/pybble.min.js
    4. Create a new project on https://cloudpebble.net
        - Select Pebble.js as the project type
        - Open `app.js` and replace the example code with the code you copied.
    5. Click the Run button
    6. :-D

Very cool

Has this project had any further development?

@pjockey soon after creating the project, Pebble company was shut down. I haven't continued work on it.
