Apply for-each loops to iterate over a dictionary by key, by value, and by item. Trace how the computer uses dictionary views to access just the dictionary values.

When programming, we use procedures to make our code more reusable and to better organize our code. Often-times, we pass parameters to a procedure so that we can change the output of the code.

Practice dictionary iteration to decide which combination of crops to plant on a farm.
