Designing type hints for optional parameters
This recipe combines the two previous recipes. It's common to define functions with fairly complex options and then add type hints around those definitions. For atomic types like strings and integers, it can make sense to write a function first, and then add type hints to the function.
In later chapters, when we look at more complex data types, it often makes more sense to create the data type definitions first, and then define the functions (or methods) related to those types. This philosophy of type first is one of the foundations for object-oriented programming.
We'll look at the two dice-based games, Craps and Zonk. In the Craps game, the players will be rolling two dice. In the Zonk game, they'll roll a number of dice, varying from one to six. The games have a common, underlying requirement to be able to create collections of dice. As noted in the Designing functions with optional parameters...
