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'})])
