Is There A Numpy "max Minus Min" Function?

Is there a numpy function that gives for a given numpy array its maximum - minimum value, i.e. numpy.max(a) - numpy.min(a) ? e.g. numpy.xxx([4,3,2, 6] = 4 since max = 6, min = 2,

Solution 1:

Indeed there is such a function -- it's called numpy.ptp() for "peak to peak".
