在python程序中添加方法

我已经完成了一个python程序，其中它打印给定序列的峰值元素。我需要在每个峰值元素之前和之后打印较低的元素

这是查找峰值元素的代码：

lead_2=['6452', '6444', '6452', '6456', '6455', '6465', '6456', '6442', '6449', '6452', '6455', '6465', '6463', '6452', '6459', '6470', '6456', '6435', '6438', '6441', '6438', '6448', '6451', '6439',

这就是我需要用来找到每个峰值元素左右的最低元素的想法

我对学习python完全是新手。请帮忙。

在我看来，您的问题可以通过以下方式解决：
给定了一个字符串格式的整数列表（前导2）
查找峰值以及前面和后面的值

观察如果lead_2[x]>lead_2[x-1]和lead_2[x]>lead_2[x+1]，则lead_2[x]被定义为峰值
让
pk_lst=表示峰值条件为真的lead_2中索引的整数列表

我们可以使用以下方法开发pk_lst：

def find_peaks(inlst):
    return [x for x in range(1,len(inlst)-1) if (int(inlst[x]) > int(inlst[x-1]) and 
            int(inlst[x]) > int(inlst[x+1]))]

列表pk_lst定义了所有峰值的索引，只需按照您认为合适的方式处理列表，例如，要打印每组的元组，请执行以下操作： 对于pk_lst中的pk

for pk in find_peaks(tst_lst):
    print((tst_lst[pk-1], tst_lst[pk], tst_lst[pk+1]))

好像是你为什么转贴的复制品？我想在那里加上这个东西。但我认为这太笨拙了。由于想法不同，我想把它放在新的位置，足以将你的程序添加到我的程序@itprorh66中，如果是的话，添加到哪里。或者我该怎么做。顺便问一下，我应该添加哪一个来代替“TSTlst”。[（1217237），（5617288），（14187215），（18407242），（22707368），（27017469）]这是我在问题中发布的程序的输出。为了进行更改，我为每个peak元素添加了一个索引（index，peak）。我必须以每一个峰值作为参考，找出每一个峰值前后的低点。我用“B”来尝试你的程序。它打印峰值附近的值。但不是最小的一个，不知道我在哪里犯了错误一旦你确定了峰，你可以使用与寻找峰相同的方法来定位峰间的谷，我把这个方法留给你来定义。

for pk in find_peaks(tst_lst):
    print((tst_lst[pk-1], tst_lst[pk], tst_lst[pk+1]))
