@ntoll visits Adafruit and talks with Ladyada about all things Python, education, communities, and the Mu editor.


Mu is a simple code editor for beginner programmers based on the feedback given to and experiences of the Raspberry Pi Foundation’s education team. Having said that, Mu is for anyone who wants to use a simple “no frills” editor.

Mu is a modal editor with modes for Adafruit’s CircuitPython, the micro:bit’s version of MicroPython and standard Python 3 (including a graphical debugger). All modes make available a REPL (either running on the connected CircuitPython or MicroPython device or as a Jupyter based iPython session in Python3 mode).

It’s written in Python and works on Windows, OSX, Linux and Raspberry Pi.
