WebNov 22, 2012 · Why don't operations on empty arrays not return empty arrays? Because functions like mean or std are expected to return a scalar. Functions that are piecewiese can (and should) return an empty array, but not the mean. I agree, this makes sense, note that: In [2]: a = np.empty((5,0)) In [3]: a.std(0) Out[3]: array([], dtype=float64) WebThe array function copies its argument’s contents into the array.Note that the type is numpy.ndarray, but all arrays are output as “array.”. When outputting an array, NumPy separates each value from the next with a comma and a space and right-aligns all the values using the same field width. It determines the field width based on the value that occupies …
