In essence, the algorithm takes the code and reformats it to
the best formatting that conforms to the style guide, even
if the original code didn’t violate the style guide.

The ultimate goal is that the code YAPF produces is as good
as the code that a programmer would write if they were
following the style guide. It takes away some of the drudgery
of maintaining your code.
