如何从json数组中生成键/值的所有组合？

import json

def generate_combinations(data):
    if isinstance(data, list):
        combinations = []
        for item in data:
            sub_combinations = generate_combinations(item)
            for sub_combination in sub_combinations:
                combinations.append(sub_combination)
        return combinations
    elif isinstance(data, dict):
        combinations = [{}]
        for key, value in data.items():
            sub_combinations = generate_combinations(value)
            new_combinations = []
            for combination in combinations:
                for sub_combination in sub_combinations:
                    new_combination = combination.copy()
                    new_combination[key] = sub_combination
                    new_combinations.append(new_combination)
            combinations = new_combinations
        return combinations
    else:
        return [data]

# 示例数据
json_data = '''
{
  "name": ["Alice", "Bob"],
  "age": [20, 30],
  "gender": ["male", "female"]
}
'''

# 解析JSON数据
data = json.loads(json_data)

# 生成所有组合
combinations = generate_combinations(data)

# 打印结果
for combination in combinations:
    print(combination)
