过滤字典列表 [英] Filter list of dictionaries

问题描述

这是我的示例:

dictlist = [{'first': 'James', 'last': 'Joule'}, 
            {'first': 'James','last': 'Watt'},
            {'first': 'Christian','last': 'Doppler'}]

我正在尝试获取姓氏.如果在模型中，则代码为:

I am trying to get the last name. If this was in a model, the code would be:

getdata = Name.objects.filter(name="Christian")
getLastName = getdata.last

我会得到"Doppler".

推荐答案

这是具有列表理解功能的非常简单的解决方案:

This is very simple solution with list comprehension:

>>> dictlist = [{'first': 'James', 'last': 'Joule'}, {'first': 'James','last': 'Watt'},{'first': 'Christian','last': 'Doppler'}]
>>> [x['last'] for x in dictlist if x['first'] == 'Christian']
['Doppler']
