    [$] Revisiting NaNs in Python
    Back in January 2020, we looked at some
    oddities in Python's handling of Not a Number (NaN) values in
    its statistics
    module    . The conversation went quiet after that, but it has been
    revived recently with an eye toward fixing the problems that were reported.
    As detailed in that earlier article, NaNs are rather strange beasts in the
    floating-point universe, so figuring out how best to deal with their
    presence is less straightforward than it might seem.
