+This exercise stub and the test suite contain several enumerated constants.
+
+Enumerated constants can be done with a NAME assigned to an arbitrary,
+but unique value. An integer is traditionally used because it’s memory
+efficient.
+
+It is a common practice to export both constants and functions that work with
+those constants (ex. the constants in the os, subprocess and re modules).
+
+You can learn more here: https://en.wikipedia.org/wiki/Enumerated_type
