Find key of object with maximum property value
dictionary, python
Solution
You can specify your own function for `key` which can do fancy stuff like getting the value for both `c` and `h` and add those up. For example using an inline-lambda:
>>> max(d, key=lambda x: d[x]['c'] + d[x]['h'])
'b'
Problem
I have dictionary of dictionaries like this. ``` d = { 'a' : {'c' : 1, 'h' : 2}, 'b' : {'c' : 3, 'h' : 5}, 'c' : {'c' : 2, 'h' : 1}, 'd' : {'c' : 4, 'h' : 1} } ``` I need to get key of the item that has highest value of `c + h`. I know you can get key of item with highest value in case like this: ``` d = { 'a' : 1, 'b' : 2, 'c' : 3 } max( d, key = d.get ) # 'c' ``` Is it possible to use the `max` function in my case?
