2列表到排序字典回到2列表（多个键值） [英] 2 Lists to Sorted Dictionary back to 2 Lists (Multiple Key Values)

问题描述

我试图拿两个列表：一个包含日期和一个包含分数，然后将它们压缩到一个字典，然后按键值排序，然后将它们转回两个列表（仍然排序）。我遇到的问题是字典不保留多个键值。我的代码如下：

  date = ['2015/07/13'，'2015/07/13' 2015/07/07'，'2015/07/06'，...] 
＃这些日期中有59个
分数= [9.5，13.9，15.5，12.9 ....]这些分数中有59个
 dictionary = dict（zip（date，Scores））
d = sorted（dictionary.items（））
 dte = [] 
 scr = [] 
在d中：
 dte.append（i [0]）
 scr.append（i [1]）$ ​​b $ b  

但是，当我打印出这些列表时，长度只有24，而不是59。多个相同的键不会退出。我想知道是否有一个简单的方法来获得所有59个排序的元素回到两个列表。我看了一些类似的其他python答案，但没有一个为我工作。理想情况下，我不想为日期创建对象（除非是最简单的方法），但是当我尝试这样做时，我会收到错误。另外，我在Python 2.7中。

解决方案

  date，Scores = zip （zip（日期，分数）））
  

I am trying to take two lists: one that contains dates and one that contains scores, then zip them into a dictionary, then sort by the key value, then turn them back in two lists (which are still sorted). The problem that I am encountering is that the dictionary does not keep multiple key values. My code is as follows:

date = ['2015/07/13', '2015/07/13', '2015/07/07', '2015/07/06',...] 
#there are 59 of these dates
Scores = [9.5, 13.9, 15.5, 12.9 .... ] #There are 59 of these scores
dictionary = dict(zip(date, Scores)) 
d = sorted(dictionary.items()) 
dte = []
scr = []
for i in d: 
    dte.append(i[0]) 
    scr.append(i[1])

However, when I print out these lists the length is only 24 in length instead of 59, which it should be. The multiple same keys are not coming back out. I was wondering if there was an easy way to get all 59 sorted elements back in two lists. I looked at some of the other python answers that were sort of similar, but none had worked for me. Ideally, I would not like to create objects for the dates (unless that is the easiest method), however when I tried to do so I kept getting errors. Also, I am on Python 2.7.

解决方案

date, Scores = zip(*sorted(zip(date, Scores)))
