Python IDE for beginners.


Thonny is a Python IDE meant for learning programming.

  • Easy to get started. Thonny comes with Python 3.7 built in, so just one simple installer is needed and you're ready to learn programming. (You can also use a separate Python installation, if necessary.) The initial user interface is stripped of all features that may distract beginners
  • No-hassle variables. Once you're done with hello-worlds, select View → Variables and see how your programs and shell commands affect Python variables
  • Simple debugger. Just press Ctrl+F5 instead of F5 and you can run your programs step-by-step, no breakpoints needed. Press F6 for a big step and F7 for a small step. Steps follow program structure, not just code lines
  • Step through expression evaluation. If you use small steps, then you can even see how Python evaluates your expressions. You can think of this light-blue box as a piece of paper where Python replaces subexpressions with their values, piece-by-piece
  • Faithful representation of function calls.Stepping into a function call opens a new window with separate local variables table and code pointer. Good understanding of how function calls work is especially important for understanding recursion
  • Highlights syntax errors. Unclosed quotes and parentheses are the most common beginners' syntax errors. Thonny's editor makes these easy to spot
  • Explains scopes. Highlighting variable occurrences reminds you that the same name doesn't always mean the same variable and helps spotting typos. Local variables are visually distinguished from globals
  • Mode for explaining references. Variables are initially presented according to simplified model (name → value) but you can switch to more realistic model (name → address/id → value)
  • Code completion. Students can explore APIs with the help of code completion
  • Beginner friendly system shell. Select Tools → Open system shell to install extra packages or learn handling Python on command line. PATH and conflicts with other Python interpreters are taken care of by Thonny
  • Simple and clean pip GUI. Select Tools → Manage packages for even easier installation of 3rd party packages

A real great ide for Python - small, fast and very helpful. But version 3.2.1 is the actual version, not 3.2.0!
