如何制作索引的随机组合列表？

import random

def generate_combinations(start, end, length):
    combinations = []
    for i in range(start, end+1):
        for j in range(start, end+1):
            for k in range(start, end+1):
                combination = [i, j, k]
                combinations.append(combination)
    random.shuffle(combinations)
    return combinations

# 示例使用范围为1到10的索引，组合长度为3
start_index = 1
end_index = 10
combination_length = 3

combinations = generate_combinations(start_index, end_index, combination_length)
for combination in combinations:
    print(combination)
