Imports​

from bisect import bisect_left, bisect_right, insort
from collections import Counter
from functools import cache
from itertools import accumulate, combinations, permutations
from math import atan2, comb, inf
from sortedcontainers import SortedList

Usage​

# Prefix sum
p = [0] + list(accumulate(nums))

# Four adjacent directions
[[dx, dy] for dx, dy in itertools.permutations([-1, 0, 1], 2) if abs(dx) != abs(dy)]

match​

match param:
    case first:
        pass
    case second:
        pass
    case _:
        pass

math​

rad = math.atan2(y2 - y1, x2 - x1)
deg = rad * math.pi / 180

sortedcontainers​

SortedList​

sortedList = SortedList()
sortedList.add((num1, num2, num3))
sortedList.remove((num1, num2, num3))
