Python Rpartition Missing Separator Visual

Create one finished image using [string parsing code], [separator] and [expected missing-separator behavior]. Depict three input strings and three-slot outputs, preserving empty strings as explicit slots. Inspect rpartition handling when the separator is absent or appears multiple times. Preserve its three-part result contract and distinguish it from partition before proposing a change. Use deliberate composition, legible visual hierarchy and no invented factual labels.

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.
