Python Prefix Removal Precision Visual

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 string diagram contrasting one literal prefix block with individual removable leading characters. Include one concrete verification step that checks the defining task detail against the supplied inputs. Use [audience] and [tone] to calibrate presentation.

Use the attached references only for the specified visual attributes. If a required reference is missing, request it before generation. Produce one finished image with a deliberate focal point, consistent geometry and clean margins. Keep any exact wording on a separate editable label layer or leave its area blank. Do not invent evidence or present an illustration as documentary proof.
