Score 527
buckets = [0] * 100
Careful - this technique doesn't generalize to multidimensional arrays or lists of lists. Which leads to the List of lists changes reflected across sublists unexpectedly problem
ANSWER 2
Score 31
You can multiply a list by an integer n to repeat the list n times:
buckets = [0] * 100
ANSWER 3
Score 25
Use this:
bucket = [None] * 100
for i in range(100):
bucket[i] = [None] * 100
OR
w, h = 100, 100
bucket = [[None] * w for i in range(h)]
Both of them will output proper empty multidimensional bucket list 100x100
