python - get list of tuples first index?

list, python, tuples

Solution

use zip if you need both

>>> r=(1,'one'),(2,'two'),(3,'three')
>>> zip(*r)
[(1, 2, 3), ('one', 'two', 'three')]

Problem

What's the most compact way to return the following: Given a list of tuples, return a list consisting of the tuples first (or second, doesn't matter) elements. For: ``` [(1,'one'),(2,'two'),(3,'three')] ``` returned list would be ``` [1,2,3] ```
