Right Split Bounded Parsing Sequence

Inputs: [Python version], [sample delimited strings], [required final fields]. Explain str.rsplit with maxsplit using a delimiter that may also occur earlier in the string. Compare split and rsplit on a three-delimiter fixture, include a no-delimiter case and distinguish an explicit separator from whitespace splitting. Do not present this as a full CSV parser. Produce a 12-second right-to-left delimiter scan stopping after the configured split count. Adapt the presentation to [audience] and [tone]. Check the defining task detail against the inputs before finishing.

Confirm required reference images and timing inputs are present before generating. Keep objects, identities, spatial relationships and light direction consistent. Render the clip when video generation is supported; otherwise supply a timed shot list, reference checklist and generation-ready prompt, labeled as a production plan. Do not claim rendered output without an actual file. Check the opening, transition and final frame against the stated counts and geometry.
