numpy ndarray size code example
Example 1: numpy get array size
myArray.shape # Returns the number of rows, columns etc. (depends on dimensions how many numbers you get)
print(a_1d.shape)
# (3,)
print(type(a_1d.shape))
# <class 'tuple'>
print(a_2d.shape)
# (3, 4)
print(a_3d.shape)
# (2, 3, 4)
Example 2: numpy array length
np_array.size
Example 3: dimensions of np array python
>>> x = np.zeros((3, 5, 2), dtype=np.complex128)
>>> x.size
30
>>> np.prod(x.shape)
30
