我是靠谱客的博主苹果外套，最近开发中收集的这篇文章主要介绍python values count_Python计算列表字典中的多个值(Python count multiple values in dictionary of list)...，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

I have been trying to count the values in a dictionary with respect to the key. However, I could not achieved desired result. I will demonstrate with more details below:

from collections import Counter

d = {'a': ['Adam','Adam','John'], 'b': ['John','John','Joel'], 'c': ['Adam','Adam','John}

# create a list of only the values you want to count,

# and pass to Counter()

c = Counter([values[1] for values in d.itervalues()])

print c

My output:

Counter({'Adam': 2, 'John': 1})

I want it to count everything in the list, not just first value of the list. Also, I want my result to be with respect to the key. I will show you my desired output below:

{'a': [{'Adam': 1, 'John': 2}, 'b':{'John': 2, 'Joel': 1}, 'c':{'Adam': 2, 'John': 1 }]}

Is it possible to get this desired output? Or anything close to it? I would like to welcome any suggestions or ideas that you have. Thank you.
