**Tell us what’s happening:**

Describe your issue in detail here.

I made a list, converted it into a 3x3 matrix and calculated the mean as below

mean = [(np.mean(a, axis=0)), (np.mean(a, axis=1)), (np.mean(a))]

When I print mean, the values if they are whole numbers show up as 4. not 4.0 and I’m not sure how to change it.

I am coding on pycharm instead of on jupyter notebook
