The operator module solution in Creative category for Safe Coasts by EnCuKou
"""Lesson 12: The operator module
Required reference re-reading: https://docs.python.org/3/library/operator.html
Today we will demonstrate the usage of Python's "operator" module in
a naval/supernatural application context.
The following functions will be covered:
* comparisons (eq, ne, le, ge, gt, lt)
* boolean logic (and_, or_, not_)
* arithmetic (add, sub, mul)
* getitem
* contains
* methodcaller
Pay close attention to the usage of methodcaller. It will be on the quiz.
