## Description:
More fixes flagged by pylint 2 that don't hurt to have before the actual pylint 2 upgrade (which I'll submit soon).

This reverts commit 672a3c7178.
DarkSky delivers relative humidity from 0-100% as a 0-1 decimal value,
so we convert it by multiplying by 100.0. Unfortunately, due to floating
point math, the display of a raw value of 0.29 ends up looking like
28.999999999999996% relative humidity.
This change rounds the value to two decimal places.
