# 生成随机整数列表
def create_list(n):
    nums = []
    for i in range(0, n):
        nums.append(random.randint(0, 100))

# 求两个列表的点积
def list_dot(K, L):
    if len(K) == len(L) and len(K) != 0:
        return sum([K[n] * L[n] for n in range(len(K))])
    else:
        return 0


# 生成随机整数numpy数组

# 计算numpy点积

    return np.dot(K, L)
