从嵌套的python列表中获取选择性数据

def get_selective_data(nested_list, condition):
    result = []
    for sublist in nested_list:
        if isinstance(sublist, list):
            result.extend(get_selective_data(sublist, condition))
        elif condition(sublist):
            result.append(sublist)
    return result

nested_list = [1, [2, 3], [4, [5, 6]], 7, [8, 9]]
condition = lambda x: x % 2 == 0  # 选择偶数

result = get_selective_data(nested_list, condition)
print(result)  # 输出: [2, 4, 6, 8]
