Sort dictionary by keys

In this video we will learn how to sort a python dictionary by its keys.

First let’s open up python and let’s create a string of the alphabet.

Next let’s use that string to create a dictionary. We will create it in reverse order, so that we can then sort it by keys.

dictionary = {string[::-1][i]:27-(i+1) for i in range(26)}

Now that we have our dictionary let’s sort it by the keys.

We import collections. we will create x which will be the sorted by keys version of our dictionary.
x = collections.OrderedDict(sorted(dictionary.items()))

So now lets compare. Here is x, which we type dict to convert it back to a normal dictionary, and here is the original dictionary.

You can see x now is alphabetic. a first then b and so on.

So there you have it, that is how you can sort a python dictionary by keys.
