How can I sort a dictionary by key?

Question

What would be a nice way to go from {2:3, 1:89, 4:5, 3:0} to {1:89, 2:3, 3:0, 4:5}? I checked some posts but they all use the "sorted" operator that returns tuples. Select the correct answer from above options

Answer 1

First thing first the Standard Python dictionaries are unordered. So, even if you sorted the (key, value) pairs, you wouldn't be able to store them in a dict in a way that would preserve the ordering. So, the easiest way of sorting a dictionary by key is to use OrderedDict, which remembers the order in which the elements have been inserted: The following example illustrates how we will use the ordered dictionary:- import collections d = {2:3, 1:89, 4:5, 3:0} od = collections.OrderedDict(sorted(d.items())) od To know more about this you can have a look at the following video tutorial:-
