numpy.size. #. numpy.size(a, axis=None) [source] #. Return the number of elements along a given axis. Parameters: aarray_like. Input data. axisint, optional. Axis along which the elements are counted.
The number of dimensions and items in an array is defined by its shape, which is a tuple of N non-negative integers that specify the sizes of each dimension. The type of items in the array is specified by a separate data-type object (dtype), one of which is associated with each ndarray.
The length of a NumPy array can be determined using the len () function, which returns the number of elements along the first dimension (axis 0) of the array. For multi-dimensional arrays, other properties such as shape can be used to get the lengths along different dimensions.
