If you have to find the union of elements that are either in the first or the second set, but not in both of them, then you need to use the symmetric difference.
This is also another math operation between sets that you have probably seen in a math class in high school.
This can be done quite easily and quickly using 2 built-in methods in Python.
Let’s start with the first one.

If you need to find whether 2 sets have the same elements, then you need to use an operation such as intersection.
This operation is known in Math and used everywhere. In Python, we have 2 built-in methods that we can use right away to find whether 2 sets have the same elements or not.

In the last article, we saw how we can find the difference between 2 sets in Python. In this article, we are going to see how to find the union of 2 sets.
This is actually quite similar to the difference.
We also have 2 ways to do the union of 2 sets in Python.

There can be cases when you may need to find the difference between 2 sets in Python. If you do not remember from high school, the difference between 2 sets means that we get the elements from the first set that are not in the second set.
We can do that quite easily in Python using the minus operator.
