Sum the second value of each tuple in a list

Question

I have structure like this:

structure = [('a', 1), ('b', 3), ('c', 2)] 

I would like to sum the integers (1+3+2) using sum() builtin method (in one line).

Any ideas?

Answer 1

sum(n for _, n in structure) 

would work.

Answer 2

sum(x[1] for x in structure) 

should work
