How to access List elements

I'd start by not calling it list, since that's the name of the constructor for Python's built in list type.

But once you've renamed it to cities or something, you'd do:

print(cities[0][0], cities[1][0])
print(cities[0][1], cities[1][1])

It's simple

y = [['vegas','London'],['US','UK']]

for x in y:
    for a in x:
        print(a)
