'Get closest value array in array of arrays.' follow up help.

[DreamingInsanity]

this could be improved using numpy right?

Yes, Numpy version of your function find_closest should work faster.

def find_closest(x, array2d):
    return array2d[np.argmin(np.abs(array2d.sum(axis=1) - x.sum()))]

Thanks for that! I will definitely go the numpy route in the future.

Thanks everyone!
