Split list into smaller lists (split in half)
...
A = [1,2,3,4,5,6]
B = A[:len(A)//2]
C = A[len(A)//2:]
If you want a function:
def split_list(a_list):
half = len(a_list)//2
return a_list[:half], a_list[half:]
A = [1,2,3,4,5,6]
B, C = split_list(A)

What is the optimal algorithm for the game 2048?
I have recently stumbled upon the game 2048 . You merge similar tiles by moving them in any of the four directions to make "bigger" tiles. After each move, a new tile appears at random empty position with a value of either 2 or 4 . The game terminates when all the boxes are filled and there are ...
What's the “big idea” behind compojure routes?
...
Compojure explained (to some degree)
NB. I am working with Compojure 0.4.1 (here's the 0.4.1 release commit on GitHub).
Why?
At the very top of compojure/core.clj, there's this helpful summary of Compojure's purpose:
A concise syntax for generating Ring handlers.
On a superficial level, ...
UTF-8, UTF-16, and UTF-32
...2 bytes for most characters.
UTF-32 will cover all possible characters in 4 bytes. This makes it pretty bloated. I can't think of any advantage to using it.
