How do you sort a dictionary by key from highest to lowest

Hi I have a dictionary that is currently the one below:

dictionary={1:'a',2:'b',3:'c'}

my desired output is to have a dictionary with the highest keys to the left and the lowest keys to the right like below:

dictionary={3:'c',2:'b',1:'a'}

how do you do that in python 3.7?

>Solution :

dict(sorted(dictionary.items(), reverse=True))
