sort dict by value python [duplicate]

Question

Assume that I have a dict.

data = {1:'b', 2:'a'} 

And I want to sort data by 'b' and 'a' so I get the result

'a','b' 

How do I do that?
Any ideas?

Answer 1

To get the values use

sorted(data.values()) 

To get the matching keys, use a key function

sorted(data, key=data.get) 

To get a list of tuples ordered by value

sorted(data.items(), key=lambda x:x[1])

Answer 2

If you actually want to sort the dictionary instead of just obtaining a sorted list use collections.OrderedDict

>>> from collections import OrderedDict >>> from operator import itemgetter >>> data = {1: 'b', 2: 'a'} >>> d = OrderedDict(sorted(data.items(), key=itemgetter(1))) >>> d OrderedDict([(2, 'a'), (1, 'b')]) >>> d.values() ['a', 'b']
