I want to get a list sorted accordingly to the following rules persons.sort(key = lambda p: (abs(p["height"] - 180), p["weight"]==75, p["weight"]))
i.e. I need it to get sorted firstly by its closeness to the height 180, then all of the weight values which are equal to 75, and then I want them to be sorted ascendingly by its weight...
I came up with the following code, which is not working...
def get_ordered_list(persons):
persons.sort(key = lambda p: p["name"] )
persons.sort(key = lambda p: (abs(p["height"] - 180), p["weight"]==75, p["weight"]))
return persons
For the following sample data, for instance,
array = [{"name": "Guido Batista", "height": 195, "weight": 110},
{"name":"Heitor Tostes", "height": 180, "weight": 75},
{"name":"Bruno Costa", "height": 180, "weight": 75},
{"name":"Joao Kleber", "height": 180, "weight": 65},
{"name":"Rafael Rodrigues", "height": 165, "weight": 110},
{"name":"Ricardo Neto", "height": 170, "weight": 70},
{"name":"Juca Carvalho", "height": 180, "weight": 77}]
I need to get the list sorted as such:
[
{"name":"Bruno Costa", "height": 180, "weight": 75},
{"name":"Heitor Tostes", "height": 180 , "weight": 75},
{"name":"Joao Kleber", "height": 180, "weight": 65},
{"name":"Juca Carvalho", "height": 180, "weight": 77},
{"name":"Ricardo Neto", "height": 170, "weight": 70},
{"name": "Guido Batista", "height": 195, "weight": 110},
{"name":"Rafael Rodrigues", "height": 165, "weight": 110},
]
This is happening because False
is a lower value than True
. Use
persons.sort(key = lambda p: (abs(p["height"] - 180), p["weight"]!=75, p["weight"]))
changing the comparison for the "weight" key.
