Python Prefix Removal Precision Narration

Inputs: [input strings], [literal prefix], [expected outputs], [Python version]. Compare str.removeprefix with str.lstrip for a literal prefix. Explain that lstrip removes a set of leading characters, while removeprefix removes one matching prefix only. Require Python 3.9 or later and include a counterexample where lstrip removes too much. Produce a 45-second explanation using the counterexample to show why character stripping is different. Include one concrete verification step that checks the defining task detail against the supplied inputs. Use [audience] and [tone] to calibrate presentation.

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.
