力扣 238. 除自身以外数组的乘积

解法

def productExceptSelf(nums):
    nums_len = len(nums)
    left = [1] * nums_len
    for i in range(1, nums_len):
        left[i] = left[i - 1] * nums[i - 1]
    # print(left)
    right = [1] *nums_len
    for i in range(nums_len - 2, -1, -1):
        right[i] = right[i + 1] * nums[i + 1]
    # print(right)
    for i in range(nums_len):
        left[i] = left[i] * right[i]
    return left
