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.)
