This chapter covered various best syntax practices that do not directly relate to Python classes and object-oriented programming. The first part of the chapter was dedicated to syntax features around Python sequences and collections, strings and byte-related sequences were also discussed. The rest of the chapter covered independent syntax elements of two groups—those that are relatively hard to understand for beginners (such as iterators, generators, and decorators) and those that are simply less known (the for…else clause and function annotations).
