how can I make the func. show all the bad values and not just one?

def get_bad_results(person_results):
        for i in person_results:
                if i[1]>i[3] or i[1]<i[2]:
                    return i[0]

test_results = [["White blood cells",8.5,2,7],
                ["Neutrophils",5.3,2.5,5],
                ["Red blood cells", 12.4, 9,15]]

a = get_bad_results(test_results)
print a

show White blood cells

instead of

White blood cells, Neutrophils

The function will return the first occurrence that fits the statement. To return all, you could save them away in a list and when the loop is done, return the list.

for i in person_results:
    bads = []
    if i[1]>i[3] or i[1]<i[2]:
        bads.append(i[0])
return bads
