Remember the sorted() example in the previous chapter. The sorted() function is generic enough that it can be used to sort more than one data structure (lists, tuples, and namedtuples) using arbitrary keys. That's the definition of a good function.
Functions such as sorted() demonstrate the ideal case. In reality, we cannot always write 100 percent generic code. There are many algorithms that have some (but not all) common steps. A good example is breadth-first search (BFS) and depth-first search (DFS), two popular algorithms ...
