numpy.MaskedArray.all() returns True if all elements are True.
MaskedArray.all (axis = None, out = None, keepdims)
axis: strong> [int or None] Axis or axes along which a logical AND reduction is performed.
out: [ndarray, optional] A location into which the result is stored.
– & gt; If provided, it must have a shape that the inputs broadcast to.
– & gt; If not provided or None, a freshly-allocated array is returned.
keepdims: [bool, optional] If this is set to True, the axes which are reduced are left in the result as dimensions with size one. With this option, the result will broadcast correctly against the input array.
Return: [ndarray, bool] A new boolean or array is returned unless out is specified, in which case a reference to out is returned.
Code # 1:
Input array: [1 2 3 -1 5] Output array: True Masked array: [1 2 - -1 5] Output array: True
Code # 2:
Input array: [1 2 3 -1 5] Masked array: [- - - - -] Output array: - -
