Thonny — The Complete Guide: A Simple Free Python Environment for Beginners and Engineering Students
Thonny was developed at the University of Tartu in Estonia and is open source (MIT). It is aimed at people writing their first lines of Python — a first-year student or an engineer who finally wants to automate a calculation — and removes almost every installation hurdle.

- One installer — Python is already inside, with no path settings.
- Visual debugger — step by step, showing how each expression is evaluated.
- Variables table — values update while the program runs.
- Simple package manager — installing numpy and matplotlib in one click.
- MicroPython — writing directly to Raspberry Pi Pico and ESP32 boards.
When to move on
As projects grow, move to Spyder for MATLAB-style scientific work, or to VSCodium for multi-file projects. The code itself carries over as it is.
