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. It was created by Aivar Annamaa, an Estonian programmer. Select Tools → Manage packages for an even easier installation of 3rd party packages. Thonny is a free and open-source integrated development environment for Python that is designed for beginners. System shell prepared for Python commandsĬlean and straightforward pip GUI. PATH and conflicts with other Python interpreters are taken care of by Thonny. Select Tools → Open system shell to install extra packages or learn to handle Python on the command line. Students can explore APIs with the help of code completion.īeginner friendly system shell. Variables are initially presented according to the simplified model (name → value), but you can switch to a more realistic model (name → address/id → value).Ĭode completion. Local and global names are visually distinguished Local variables are visually distinguished from globals. Highlighting variable occurrences reminds you that the same name doesn't always mean the same variable and helps spot typos.

Thonny's editor makes these easy to spot.Įxplains scopes. Unclosed quotes and parentheses are the most common beginners' syntax errors. A good understanding of how function calls work is crucial for understanding recursion. Stepping into a function call opens a new window with separate local variables table and code pointer. You can think of this light-blue box as a piece of paper where Python replaces subexpressions with their values, piece-by-piece.įaithful representation of function calls. If you use small steps, then you can even see how Python evaluates your expressions. Steps follow program structure, not just code lines. Press F6 for a big step and F7 for a small step. Just press Ctrl+F5 instead of F5, and you can run your programs step-by-step no breakpoints are needed. ![]() ![]() Once you're done with hello-worlds, select View → Variables and see how your programs and shell commands affect Python variables. ![]() (You can also use a separate Python installation, if necessary.) The initial user interface is stripped of all features that may distract beginners. Thonny comes with Python 3.7 built-in, so just one simple installer is needed, and you're ready to learn to program. Thonny is an Open Source Python IDE for beginners.Įasy to get started.
