Using the two lists below as an example:
x = [1, 2]
y = [1, 2]
And testing:
x == y
x is y
The first test gives True and the second gives False. Why the result is different in both cases?

== compares whether variables have the same value.
is checks whether both refer to the same object or not.
x = [1, 2]
y = [1, 2]
x == y (true)
x is y (false)
x and y have the same value [1, 2], but they are different objects.

Just need to complete saying because in this case are equal but are different objects, because this does not always happen. If x = 2 and y = 2, x is y will be True, different from the example of the question.

Greetings Thiago. I would recommend a little more caution when creating a question here on the site, because the system has automatic penalties for users with many closed questions. What I usually recommend doing before asking is to access the chat and discuss with staff about the possible question; if it is duplicated probably someone will already know how to indicate. I am always online there and will help in the possible, especially in Python. Just try not to be penalized for something simple even if you have the best intentions.
