sort multiple-level dict

https://stackoverflow.com/questions/42247379/how-to-sort-multi-level-dictionary-by-its-value

test_dict = {'Items1':{'name':'Homer', 'age':39},'Items2':{'name':'Bart', 'age':10},'Items3':{'name':'Json','age':20}}

import pandas as pd
df = pd.DataFrame(test_dict)
result = df.sort_values(by='age', axis=1, ascending=True).apply(OrderedDict)

Resulting with

Items2     {u'age': 10, u'name': u'Bart'}
Items3     {u'age': 20, u'name': u'Json'}
Items1    {u'age': 39, u'name': u'Homer'}

Other Method:

from collections import OrderedDict

test_dict = {
    'Items1':{'name':'Homer', 'age':39},
    'Items2':{'name':'Bart', 'age':10},
    'Items3':{'name':'Json','age':20}
}

sorted_dict = OrderedDict()
sorted_keys = sorted(test_dict, key=lambda x: test_dict[x]["age"])     

for key in sorted_keys: 
    sorted_dict[key] = test_dict[key]

print(sorted_dict)

Output:

OrderedDict([('Items2', {'age': 10, 'name': 'Bart'}), ('Items3', {'age': 20, 'name': 'Json'}), ('Items1', {'age': 39, 'name': 'Homer'})])
