Python Nested Lists 嵌套1.基础内容1） 嵌套列表是可以包含其他列表的列表，可以用来表示二维或多维的数据结构 嵌套循环（nested loops）是一种常用的遍历嵌套列表中所有元素的方法，需要在外层循环控制行索引，在内层循环控制列索引。2）嵌套列表可以用下标（index）来访问和修改其中的元素，需要两层或多层的索引3）嵌套列表可以用len()函数来获取其长度，即其中包含的子列表

Given a nested list of integers, implement an iterator to flatten it.
Each element is either an integer, or a list -- whose elements may also be integers or other lists.
Example 1:

一、把嵌套列表压平为一层列表def flatten(nested_list):
'''
这是把嵌套列表压平为简单列表并返回的函数
:参数 nested_list:一个嵌套列表
'''
#先定义一个空列表，用于存储我们提出出来的元素，
# 这也是最终要返回的那个列表
new_list = []
#遍历原始的嵌套列表
