+Maximum Line Length
+===================
+
+Keeping lines under the `PEP 8 recommendation <https://www.python.org/dev/peps/pep-0008/#maximum-line-length>`_ of 79 (or 99) 
+characters helps readers easily parse the code.
+
+Wrapped lines should conform to the following guidelines.
+
+1. The first argument should not be attached to the opening parenthesis. 
+2. One, and only one, indent should be used.
+3. Each argument should fall on its own line.
+4. The terminating element, :code:`);`, should be placed on the final line by itself.
