I have a list of dicts like below:
lod = [
{'name': 'Tom', 'score': 60},
{'name': 'Tim', 'score': 70},
{'name': 'Tam', 'score': 80},
{'name': 'Tem', 'score': 90}
]
I want to get {'name': 'Tem', 'score':90}
but I only can do below:
max(x['score'] for x in lod)
This only return the value 90
.
How can I get the whole dict?
You can use the key function of max
:
>>> lod = [
... {'name': 'Tom', 'score': 60},
... {'name': 'Tim', 'score': 70},
... {'name': 'Tam', 'score': 80},
... {'name': 'Tem', 'score': 90}
... ]
...
>>> max(lod, key=lambda x: x['score'])
{'name': 'Tem', 'score': 90}
Just pass your list to max
, like this:
>>> from operator import itemgetter
>>> lod = [
... {'name': 'Tom', 'score': 60},
... {'name': 'Tim', 'score': 70},
... {'name': 'Tam', 'score': 80},
... {'name': 'Tem', 'score': 90}
... ]
>>> max(lod, key=itemgetter('score'))
{'score': 90, 'name': 'Tem'}
I dont know whether sorting
is time consuming,
>>>sorted(lod, key=lambda x:x['score'])[-1]
{'name': 'Tem', 'score': 90}
