Python中JSON中元素的翻转顺序

Question

I can't seem to find a solution for this but suppose I have JSON data:

data = [{"color":"blue","score":"3"},{"color":"red","score":"2"},....]

How do I reverse the order of color and score so it's:

data = [{"score":"3","color":"blue"},{"score":"2","color":"red"},....]

Answer 1

While the order of the items does not matter, if you really wanted to have a certain order you could use an OrderedDict .

>>> from collections import OrderedDict
>>> data = [OrderedDict([("score", "3"),("color", "blue")])]
>>> json.dumps(data)
'[{"score": "3", "color": "blue"}]'

Answer 2

How I write in comment you should sort your dicts and convert them into OrderedDicts

from collections import OrderedDict

a = {'score':3, 'color':'red'}
b = {'score':1, 'color':'yellow'}
lst = []

for d in [a,b]:
    temp = OrderedDict()
    for k in sorted(d, reverse=True):
        temp.setdefault(k, d[k])
    lst.append(temp)

OUTPUT: [OrderedDict([('score', 3), ('color', 'red')]), OrderedDict([('score', 1), ('color', 'yellow')])]
