238. Product of Array Except Self - LeetCode

class Solution:
    def productExceptSelf(self, nums: list[int]) -> list[int]:
        result = [1] * len(nums)
        l = r = 1
        for i in range(len(nums)):
            result[i] *= l
            l *= nums[i]
            result[-1 - i] *= r
            r *= nums[-1 - i]
        return result
