What are the steps to create 1D, 2D and 3D arrays?

Answer»
  • 1D array creation:
IMPORT numpy as npone_dimensional_list = [1,2,4]one_dimensional_arr = np.array(one_dimensional_list)print("1D array is : ",one_dimensional_arr)
  • 2D array creation:
import numpy as nptwo_dimensional_list=[[1,2,3],[4,5,6]]two_dimensional_arr = np.array(two_dimensional_list)print("2D array is : ",two_dimensional_arr)
  • 3D array creation:
import numpy as npthree_dimensional_list=[[[1,2,3],[4,5,6],[7,8,9]]]three_dimensional_arr = np.array(three_dimensional_list)print("3D array is : ",three_dimensional_arr)
  • ND array creation: This can be achieved by giving the ndmin attribute. The below example demonstrates the creation of a 6D array:
import numpy as npndArray = np.array([1, 2, 3, 4], ndmin=6)print(NDARRAY)print('Dimensions of array:', ndArray.ndim)
