问题描述
如何从字典列表中获取给定键的值?
How do I get a given key's value from a list of dictionaries?
mylist= [
{
'powerpoint_color': 'blue',
'client_name': 'Sport Parents (Regrouped)'
},
{
'sort_order': 'ascending',
'chart_layout': '1',
'chart_type': 'bar'
}
]
mylist"中的字典数量未知,我想查找键sort_order"所附加的值.
The number of dictionaires in 'mylist' is unknown and I want to find the value attached to the key 'sort_order'.
我的失败尝试:
for key in mylist:
for value in key:
print key['sort_order']
谢谢
推荐答案
mylist= [{'powerpoint_color': 'blue', 'client_name': 'Sport Parents (Regrouped)'}, {'sort_order': 'ascending', 'chart_layout': '1', 'chart_type': 'bar'}]
print [d["sort_order"] for d in mylist if "sort_order" in d][0]
结果:
ascending

您还可以将所有字典组合成一个字典,然后访问它:
You could also combine all of the dictionaries into a single dict, and access that:
combined_d = {key: value for d in mylist for key,value in d.iteritems() }
print combined_d["sort_order"]
