Accessing The Elements In Matrices




  1. Double bracket approach
  2. import numpy as np
    
    my_matrix = np.array([[1,2,3],[4,5,6],[7,8,9]])
    
    # double bracket approach
    print(my_matrix[0][1])


  3. Single bracket approach
  4. import numpy as np
    
    my_matrix = np.array([[1,2,3],[4,5,6],[7,8,9]])
    
    # single bracket approach
    print(my_matrix[0, 1])
