Human: Can you show me a Python program to concatenate two objects in a Python script. Assistant: 
Here is a Python program to concatenate two objects in a Python script

import numpy as np

def concat_two_objects(first, second):
    """
    Concatenates two objects
    :param first: first object
    :param second: second object
    :return: concatenated object
    """
    return first + second

# Enter the matrix
matrix1 = np.array([[1,2,3],[4,5,6],[7,8,9]])
matrix2 = np.array([[10,11,12],[13,14,15],[16,17,18]])

# Calling the function
print((concat_two_objects(matrix1, matrix2)))

#Example Output

# [[11 13 15]
#  [17 19 21]
#  [23 25 27]]

#Remember to inspect code for bugs.
