I would often prefer to break it into two steps:
temp = (f(x) for x in nums)
results = [e for e in temp if e>0]
Others will dislike the extra line and temp var, which is one reason
it isn't among the several solutions previously suggested. Are these
differences big enough (or the solutions obscure enough) that the
variation is itself a cost of the current situation?
