Question

What are the steps to use shape for a 1D array, 2D array and 3D/ND array respectively in NumPy?

Answer 1

1D Array:

num=[1,2,3] if not added

print(‘\nshpae of 1d ‘,num.shape)

2D Array:

num2=[[1,2,3],[4,5,6]] if not added

print(‘\nshpae of 2d ‘,num2.shape)

3D or ND Array: 

num3=[[[1,2,3],[4,5,6],[7,8,9]]] if not added

print(‘\nshpae of 3d ‘,num3.shape)
