Python Programming Workspace

No state comparison yet

Run a program to compare visible values before and after every instruction.

Move to an if, elif, or while step to investigate its result.

Run a program with a function call, then step into that function.

When Python stops, this view will explain the message and show a practical next check.

Open Variables, choose a name, and select Watch to pin it here.

Run a program containing a list, tuple, dictionary, set, or string.

Run a program that mutates or reassigns a list, dictionary, or set.

Run the program to see which executable lines Python reached.

Run code containing a for or while loop.

INPUT PLAYGROUND

Enter one response per line. Python consumes them from top to bottom whenever input() runs.

No input values prepared.

COMPARE TWO RUNS

Capture the current trace as Run A or Run B, then inspect their first difference.

Run A and Run B are waiting.

Use the star beside the playback controls to save an important trace moment.
