I have a list of a list of integers. The= lists are long so i cant really show an actual example of on of the lists,= but I know that they contain only the integers 1,2,3,4. so for example.
s2 =3D [[1,2,2,3,2,1,4,4],[2,4,3,2,3,1]]

I am calculating the product, sum, max, min.= ... of each list in s2 but I get negative or 0 for the product for a lot of= the lists. (I am doing this in ipython)

for x in s2:
=C2=A0 =C2=A0 print('len =3D '= ;, len(x), 'sum =3D ', sum(x), 'prod =3D ', prod(x), 'm= ax =3D ', max(x), 'min =3D ', min(x))

...
('len =3D ', 100, 'sum =
=3D ', 247, 'prod =3D ', 0, 'max =3D ', 4, 'min =3D=
 ', 1)
