Contour label demo would benefit from some more info and/or references.

Problem

Hi there

• I found the first example in the contour label demo to be unclear because it uses the format statements %r and %% without explanation or reference.
• I have included a screenshot of the part of the docs that I am referring to.

Suggested Improvement

• I think it would improve the documentation to include further information on this or provide a reference for further reading.

All the best.

This is "only" standard Python percent formatting (%r formatting with repr(), %% being a literal percent).

Anyway, The formatting has been replaced in #18976
For the updated version see https://matplotlib.org/devdocs/gallery/images_contours_and_fields/contour_label_demo.html

Thanks Tim, that's a lot clearer now I think. 😄
