Thonny

Thonny is a beginner-friendly Python IDE (Integrated Development Environment) that allows users with little to no programming knowledge to take their first step on the road to mastering the Python programming language.

Built from the ground up by the developer Aivar Annamaa, this education tool is regarded as one of the best tools for teachers to provide their students with a streamlined and uncluttered programming environment for learning fundamentals of programming, slowly expanding their coding and problem-solving capabilities, and getting them ready to tackle more complicated programming tasks.

The cornerstone of this programming environment is Thonny’s editor, which features a barren user interface that promotes the bare minimum of tools, and a wide variety of background services that can enable novices to accelerate their learning and optimize their workflow before they move to a more advanced IDE platform that caters to the needs of enthusiasts and professionals.

Thonny is distributed online as a standalone automated installer that will deploy on a PC everything that is needed for learning the basics of Python programming.

Even the automated installer is simplified to eliminate the chance of overwhelming novices during its short procedure of getting the app ready for first use. Once inside the app, students will have to get used to a very simple user interface that promotes fast and easy learning.

• No-hassle variables
• Simple debugger
• Step through expression evaluation
• Faithful representation of function calls
• Highlights syntax errors
• Explains scopes

Thonny app promotes the use of no-hassle variables, an advanced debugger that can perform step-by-step debugging where students can learn to better follow program structure, how to step through expression evaluation, how to handle function calls, and more.

Coding is simplified with automatic highlighting of syntax errors, code completion, and highlighting differences between global and local variables.

Also included are support for a beginner-friendly system shell for installing extra packages, plug-in compatibility for uploading code to several online destinations, and even a mod for a dark GUI theme.

What’s New

• Fixed an issue affecting PyPI package search functionality.
• Added support for selecting the ESP32-C6 family in the esptool dialog.
• Updated the bundled esptool to a newer version.
• Improved Linux compatibility by resolving a missing dbus-next dependency.
• Updated application metadata (org.thonny.Thonny.appdata.xml).

Thonny is 100% FREE and can be easily installed with the help of an automated installer on Windows 7, 8.1, 10, or 11. Users on Windows Vista or XP will need to follow a different installation procedure, where Thonny and Python need to be installed separately.

Check the installation instructions on the official Thonny website. Windows 8 and 10 users may also receive an “unsafe” SmartScreen prompt from Windows Defender. That is a known issue, and users simply need to click on “More info” and “Run anyway”.
