Python Groupby Adjacent Runs Audio

Inputs: [Python version], [input sequence], [key function]. Explain itertools.groupby as grouping consecutive equal keys rather than all equal keys globally. Use the sequence A,A,B,A as a minimal fixture. Materialize each group before advancing, contrast with a deliberately sorted copy, and explain that sorting changes order. Produce a 45-second explanation reading the three adjacent runs and the sorted alternative. Adapt the presentation to [audience] and [tone]. End with a concrete check of the defining task detail against the inputs.

Use only the supplied facts and approved wording. If a necessary script or timing reference is missing, ask for it first. Produce the audio when supported; otherwise return the complete spoken script with pauses and a short production cue sheet, clearly labeled as a script. Use original voices and keep speech intelligible without music. Never claim an audio file exists unless it was generated.
