i agree! that's fast, but not clear solution.

Fast? Copying half the list to another place (O(n) space)? It can easily be done with O(n) time and O(1) space.

How?

Iterate over sequence and collect sum. <a href="https://docs.python.org/2/library/itertools.html">https://docs.python.org/2/library/itertools.html</a>#itertools.islice

Why would you use a lambda here? -1 for that (based on PEP8, in which the use of lambda's that are bound to an identifier is discourages).

Labda looks like an overkill here

It's great. The lambda function makes the code shorter and cleaner. Put a plus.

List but not the least
