Library uses short argument names

`pylint` suggests using argument names with at least 3 letters. This library uses argument names of shorter length, and while these warnings have been disabled for now, they should be considered for renaming. This may require the rework of Learn Guides and other references to code snippets.

Start by running pylint on the library and inventorying argument names shorter than three letters. Then search the Learn Guides and other referenced code snippets for those names; the work is done when the intended renames and affected references are fully identified and consistently updated.
