a = np.array([[1, 2], [3, 4]])
b = np.array([[5, 6]])

# Concatenate rows
np.concatenate((a, b), axis=0) 
#array([[1, 2],
#       [3, 4],
#       [5, 6]])

# Concatenate columns
np.concatenate((a, b.T), axis=1) 
#array([[1, 2, 5],
#       [3, 4, 6]])

# Concatenate flattened values
np.concatenate((a, b), axis=None) 
#array([1, 2, 3, 4, 5, 6])

# Example 1: Use concatenate() to join two arrays
con = np.concatenate((arr, arr1))
print(con)

# Example 2: Use concatenate() with axis
con = np.concatenate((arr, arr1), axis=1)
print(con)

# Example 3: Use np.stack() function to Join Arrays
con = np.stack((arr, arr1), axis=1)
print(con)

# Example 4: Use np.hstack() function
con = np.hstack((arr, arr1))
print(con)

# Example 5: Use np.vstack() function 
con = np.vstack((arr, arr1))
print(con)

# Example 6: Use np.dstack() function to Stacking Along Height (depth)
con = np.dstack((arr, arr1))
print(con)
