It would seem much more natural to me to have these methods in their own file, grouped nicely in sub-directories. But it seems this is not the python way. Sigh.

You've completely missed the point.  99% of the time if you can't write 
down what a method does in at most half a dozen lines, the method is 
screaming out to be refactored.  Rightly or wrongly you've already 
rejected that option, although I suspect that rightly is nearer the mark 
in this case on the grounds that practicality beats purity.
