* Editor: Multi-language editor with function/class browser, code analysis features (pyflakes and pylint are currently supported), code completion, horizontal and vertical splitting, and goto definition. * Interactive Console: Python or IPython consoles with workspace and debugging support to instantly evaluate the code written in the Editor. It also comes with Matplotlib figures integration. * Documentation Viewer: Show documentation for any class or function call made either in the Editor or a Console. * Variable Explorer: Explore variables created during the execution of a file. Editing them is also possible with several GUI based editors, like a dictionary and Numpy array ones. * Find in Files: Supporting regular expressions and mercurial repositories. * File Explorer: The file explorer pane is a file/directory browser allowing the user to open files with the internal editor or with the appropriate application (Windows only). * History Log: The history log plugin collects command histories of Python/IPython interpreters or command windows.

* No-hassle variables. Once you're done with hello-worlds, select View → Variables and you 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. * 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).
