Thonny (/ˈθɒni/ THON-ee) is an integrated development environment for Python that is designed for beginners. It was created by Aivar Annamaa, an Estonian programmer. It supports different ways of stepping through code, step-by-step expression evaluation, detailed visualization of the call stack and a mode for explaining the concepts of references and heap.[1]


  • Line numbers
  • Statement stepping without breakpoints
  • Live variables during debugging
  • Stepping through evaluation of the expressions (expressions get replaced by their values)
  • Separate windows for executing function calls (for explaining local variables and call stack)
  • Variables and memory can be explained either by using simplified model (name → value) or by using more realistic model (name → address/id → value)
  • Simple pip GUI
  • Support for CPython and MicroPython
  • Support for running and managing files on a remote machine via SSH
  • Possibility to log user actions for replaying or analyzing the programming process



The program works on Windows, macOS and Linux. It is available as a binary bundle including the recent Python interpreter[3] or pip-installable package.[6] It can be installed via the operating-system package manager on Debian, Raspberry Pi, Ubuntu and Fedora.


Thonny has received favorable reviews from Python and computer science education communities.[7][8][9] It has been a recommended tool in several programming MOOCs.[10][11] Since June 2017 it has been included by default in the Raspberry Pi's official operating system distribution Raspberry Pi OS.[12]
