How to reverse dictionary order? : Pythoneo

Let’s learn how to reverse dictionary order in Python.

Reverse a dictionary in python

To change the order it is enough just to change a and b places in the dictionary.

Just like that:

languages_I_know = {1: 'Javascript', 2: 'Kotlin', 3: 'Python'}
print(languages_I_know)
reversed_languages_I_know = {a: b for b, a in languages_I_know.items()}
print(reversed_languages_I_know)

And that’s how the order of dictionary elements is changed.
