In a recent thread on python-ideas (https://mail.python.org/pipermail/python-ideas/2015-January/030817.html), it was concluded that Python should not have a range-like type for floats in the stdlib, but there should be some simple discussion of the alternatives in the docs.

The attached diff describes the issues, demonstrates the simplest reasonable algorithm, and links to a recipe on ActiveState (which builds the same algorithm into a lazy sequence, and links to other recipes with different alternatives).
