I can't speak for "python", but our informal coding standard
asked for single blank lines between blocks of code that handled
different aspects/steps of a problem, and single lines between
functions/methods, and double blank lines between class or
function definitions at the module level of indentation.

Blank lines are a readability tool as much as clear indentation is.
Depending on the definition of "sparingly", this may be the one
piece of Guido's advice that we've ever ignored... :-)
