           • Creating two dimensional array of 3 rows and 4 columns with all ones as value :

              import numpy as np
              a = np.ones((3,4))
              print(a)
          Output:

              [[1. 1. 1. 1.]

               [1. 1. 1. 1.]
               [1. 1. 1. 1.]]
           • Creating two dimensional array of 3 rows and 3 columns with all zeroes as value:

              import numpy as np

              a = np.zeros((3,3))

              print(a)
          Output:

              [[0. 0. 0.]
               [0. 0. 0.]

               [0. 0. 0.]]
           • Creating two dimensional array of 3 rows and 4 columns with all six as value:

              import numpy as np

              a = np.full((3,4),6)
              print(a)
          Output:

              [[6 6 6 6]

               [6 6 6 6]

               [6 6 6 6]]
           • We can create two dimensional (2-D) arrays by passing nested lists to the array() function.

              import numpy as np

              a = np.array([11,'Arshia',93],[15,'Riddhi',95])
              print(a)
          Output:

              [[11,'Arshia',93]

               [15,'Riddhi',95]]
