The tutorial page for classes starts with "Compared with other programming languages". While object-oriented programming and classes are popular in many programming languages, not everyone learning about Python's classes is familiar with the concept. I teach both new programmers and programmers who have heard of object-oriented programming but never created a class before. I think the first paragraph on this page should be a brief explanation of the use of classes. It may also be a good idea to have a "Why classes?" section explaining the uses of classes in more detail.
This particular PR seems fine. I'll review it in more detail later. In general, the tutorial is intended to be a structured overview of the language rather than a how-to-program lesson. Concepts are usually linked to the glossary or external sources and some information is communicated indirectly by the examples.
