Sort Python dictionaries by key
Sort Python dictionaries by key Even though dictionaries in Python are unordered, we can use this following technique to sort the dictionaries: >>> import collections >>> d = {2:3, 1:89, 4:5, 3:0} >>> od = collections.OrderedDict(sorted(d.items())) >>> od OrderedDict([(1, 89), (2, 3), (3, 0), (4, 5)]) And the best thing is we can still using that collection just like our old dictionary: >> od[1] 89 >>> for k, v in od.iteritems(): print k, v 1 89 2 3 3 0 4 5 Note: the only difference is that we use iteritems() instead of items(). But it will be the same in python 3 (items()) References: http://stackoverflow.com/questions/9001509/how-can-i-sort-a-dictionary-by-key http://me.dangtrinh.com download file now
