? get negative from prod(x) when x is positive integers

[Vincent Davis]

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 = [[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:
print('len = ', len(x), 'sum = ', sum(x), 'prod = ', prod(x), 'max = ',
max(x), 'min = ', min(x))

....

('len = ', 100, 'sum = ', 247, 'prod = ', 0, 'max = ', 4, 'min = ', 1)
('len = ', 100, 'sum = ', 230, 'prod = ', -4611686018427387904, 'max =
', 4, 'min = ', 1)
('len = ', 100, 'sum = ', 261, 'prod = ', 0, 'max = ', 4, 'min = ', 1)

......

('prod =', 0, 'max =', 4, 'min =', 1)
('prod =', 1729382256910270464, 'max =', 4, 'min =', 1)
('prod =', 0, 'max =', 4, 'min =', 1)

.....


Whats going on?
