Any ideas how to solve this-

Given a list of tuples default buckets and a list of scores, compare each item in scores with every tuple in default_bucket and count how many fall under such buckets. Output has to be a dictionary with tuple as keys and the count as values.

default_bucket = [(300,400), (401, 500), (501, 600), (601, 700), (701, 800), (801, 900), (901, 1000)]

scores = [420, 410, 908, 700, 450, 310, 200, 555, 996, 1000]

output = {(300, 400): 2, (401, 500): 3, (501, 600): 1, (601, 700): 1, (901, 1000): 3}

eg: 420 is lt 500 and gt 401 so the count of (401, 500) increases by 1.
410 falls between 401 and 500 so count increments by 1.
450 falls 401 and 500 so count increments by 1. So the count for this tuple is 3 .
