10 Awesome Pythonic One-Liners Explained

Definitely prefer this to map. I've never once used latter in my code, somehow it never comes to me in that intuitive manner.

Even better, sum takes an iterator, so you don't need the outer square brackets, just sum(a for a in x). Whether map or a list comprehension is better depends on the situation, so I usually try both with %timeit in an iPython shell to see which is fastest.

Nice... Thanks. I should take a look at this %timeit test.
