Optimizing the Number of Arguments in Functions

Having functions or methods that take too many arguments is a sign of bad design (a code smell). Let’s explore ways of dealing with this issue.

The first alternative is a more general principle of software design—reification (creating a new object for all of those arguments that we are passing, which is probably the abstraction we are missing). Compacting multiple arguments into a new object is not a solution specific to Python, but rather something that we can apply in any programming language.
