Better way to do solve no. 9

p = np.random.randint(9, size=(3,3))

Saves the overhead of reshaping.

rougier commented

Are you referring to "9. Create a 3x3 matrix with values ranging from 0 to 8 (★☆☆)"?
I think your solution is not equivalent, is it?

sominw commented

@rougier I think it is. It does output the same result- 3 x 3 matrix (in randomized manner), where values may/may not be unique (but strictly in the specified range. Please let me know otherwise?

Z = np.arange(9).reshape(3,3) will provide a sorted matrix.

Maybe I wrote the question badly. In my mind, you need to have all values from 0 to 8. I used "ranged" with reference to the arange method, maybe this the confusing part:

>>> print (np.arange(9).reshape(3,3))
array([[0, 1, 2],
       [3, 4, 5],
       [6, 7, 8]])

Ah, I see. I thought otherwise. No issues :)
