"map" is what comes to mind first for me, but that's probably because

 1) Before I learned Python, I learned other more functional languages
    where map was the definitive answer.

 2) When I first learned Python it didn't have list comprehensions. 
 
That said, "map" seems to be frowned upon by the Python community for
reasons I've never really understood, and most people are going to
prefer reading a list comprehension.  "What most people are going to
prefer reading" does matter...
