Why is this is some python files but not in some others?

Thanks for asking. As documented in our style guide
(https://google.github.io/styleguide/pyguide.html?showone=Shebang_Line#Shebang...),
it's only needed for those script that run from shell. That's why you don't find
that line in the quality_assessment package.
