 Units of functionality are encapsulated in methods - similar to _functions_ in other languages. A method can optionally be defined with positional arguments, and/or keyword arguments that are defined and called using the `:` syntax. Methods either implicitly return the result of the last evaluated statement, or can explicitly return an object via the `return` keyword. Methods are invoked using `.` syntax.
