如何将JSON列表中的每个元素相互组合

import json

def combine_elements(json_list):
    result = []
    if len(json_list) == 1:
        return json_list[0]
    else:
        for i in range(len(json_list)):
            current_element = json_list[i]
            remaining_elements = json_list[:i] + json_list[i+1:]
            combinations = combine_elements(remaining_elements)
            if isinstance(combinations, list):
                for combination in combinations:
                    result.append([current_element] + combination)
            else:
                result.append([current_element] + [combinations])
    return result

# 示例数据
json_data = '[1, 2, 3, 4]'
json_list = json.loads(json_data)

# 调用函数进行组合
combinations = combine_elements(json_list)

# 打印结果
print(json.dumps(combinations))
