比较嵌套列表中的项(Python)

def compare_nested_lists(list1, list2):
    if len(list1) != len(list2):
        return False
    
    for i in range(len(list1)):
        if isinstance(list1[i], list) and isinstance(list2[i], list):
            if not compare_nested_lists(list1[i], list2[i]):
                return False
        else:
            if list1[i] != list2[i]:
                return False
    
    return True

# 示例数据
nested_list1 = [1, [2, 3], [4, [5, 6]]]
nested_list2 = [1, [2, 3], [4, [5, 6]]]
nested_list3 = [1, [2, 3], [4, [5, 7]]]

# 比较嵌套列表
print(compare_nested_lists(nested_list1, nested_list2))  # 输出：True
print(compare_nested_lists(nested_list1, nested_list3))  # 输出：False
