Hi, why is
bool(np.dtype(np.float)) False
? I came across this when using this python idiom: def f(dtype=None): ....if not dtype: ........print 'using default dtype' If there is no good reason to have a False truth value, I would vote for making it True since that is what one would expect (no?) N.

The default truth value probably should be True, but not for this reason. The correct idiom to use is this: def f(dtype=None): if dtype is None: print 'using default dtype' -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco
