-	-
`np.array([1,2,3])`	One dimensional array
`np.array([(1,2,3),(4,5,6)])`	Two dimensional array
`np.zeros(3)`	1D array of length 3 all values 0
`np.ones((3,4))`	3x4 array with all values 1
`np.eye(5)`	5x5 array of 0 with 1 on diagonal (Identity matrix)
`np.linspace(0,100,6)`	Array of 6 evenly divided values from 0 to 100
`np.arange(0,10,3)`	Array of values from 0 to less than 10 with step 3 (eg [0,3,6,9])
`np.full((2,3),8)`	2x3 array with all values 8
`np.random.rand(4,5)`	4x5 array of random floats between 0â1
`np.random.rand(6,7)*100`	6x7 array of random floats between 0â100
`np.random.randint(5,size=(2,3))`	2x3 array with random ints between 0â4
