🇺🇦 Thonny 4 is dedicated to Ukraine fighting the Russian invasion. Please support Ukraine! 🇺🇦
Installation instructions
Windows
Default Windows installer (thonny-4.1.0.exe) is now 64-bit and comes with Python 3.10 -- this means it is suitable only for 64-bit Windows 8.1, 10 and 11. For Windows 7, 8 and for 32-bit Windows 10 use thonny-py38-4.1.0.exe which comes with 32-bit Python 3.8.
macOS
thonny-4.1.0.pkg contains universal2 build of Python 3.10 -- this means it is suitable both for Arm (M1, M2) and Intel Macs.
Linux
thonny-4.1.0.bash is a script, which downloads and installs thonny-4.1.0-x86_64.tar.gz (with Python 3.10) when run on x86_64 machines. On other platforms it tries to use system python3 (creates a virtual environment for Thonny and installs thonny and its dependencies there).
