How to combine elements from 2 lists together with a condition

by 
combs = []
list1 = [1,2,3]
list2 = [3,1,4]

for x in list1:
    for y in list2:
        if x != y:
            combs.append((x, y))

print(combs)
print(combs[2][0])
print(combs[2][1])

results in:

[(1, 3), (1, 4), (2, 3), (2, 1), (2, 4), (3, 1), (3, 4)]
2
3

But there’s also a more elegant solution using list comprehensions:

list1 = [1,2,3]
list2 = [3,1,4]
combs2 = [(x, y) for x in list1 for y in list2 if x != y]
print(combs2)
