Haven't seen mentioned yet that .html files and legacy tools have an extremely lax historical attitude towards whitespace. People of a certain age came to the web understanding that a space is the same as a tab is the same as a line feed, as far as browsers are concerned. The (increasingly common) practice on minifying is just one offspring of that history, which is, to the main point, not shared with Python.
