If I have a numpy dtype, how do I automatically convert it to its closest python data type? For example,

numpy.float32 -> "python float"
numpy.float64 -> "python float"
numpy.uint32  -> "python int"
numpy.int16   -> "python int"

I could try to come up with a mapping of all of these cases, but does numpy provide some automatic way of converting its dtypes into the closest possible native python types? This mapping need not be exhaustive, but it should convert the common dtypes that have a close python analog. I think this already happens somewhere in numpy.
