[python] How to extract the n-th elements from a list of tuples?

I'm trying to obtain the n-th elements from a list of tuples.

I have something like:

elements = [(1,1,1),(2,3,7),(3,5,10)]

I wish to extract only the second elements of each tuple into a list:

seconds = [1, 3, 5]

I know that it could be done with a for loop but I wanted to know if there's another way since I have thousands of tuples.

This question is related to python list tuples

The answer is

n = 1 # N. . .
[x[n] for x in elements]
