Hi

I want to do basic math with a list.

a = [1, 2, 3, 4, 5, 6, 7, 8]

for idx, num in enumerate(a):
     print(idx, num)

This works, but say I want to print the item value at the next index as well as 
the current.

for idx, num in enumerate(a):
     print(num[idx + 1], num)

I am expecting 2, 1.

But am receiving

TypeError: 'int' object is not subscriptable

Why?

I think you want a[idx+1], not num[idx+1].

Bear in mind that you will get IndexError for the last item in the list.
