# Python – Check if two sets are disjoint sets

In this tutorial, we will look at how to check whether two sets are disjoint sets or not in Python with the help of examples.

Two sets are said to be disjoint sets if they do not have any common elements between them. That is, the intersection of the sets is an empty set. Let’s look at an example.

You can see that sets A and B in the above example do not have any shared elements between them and thus are disjoint sets.

Python comes with a built-in set data structure to implement a set. It also has a number of additional functions to help you with common operations on sets such as union, intersection, difference, etc.

To check if two sets are disjoint sets or not in Python, you can use the set `isdisjoint()` function. The following is the syntax:

```# check if sets a and b are disjoint sets
a.isdisjoint(b)```

It returns `True` if the sets are disjoint and `False` otherwise. Let’s look at an example.

```# create two sets
a = {1,2,3}
b = {4,5}
# check if the sets are disjoint
a.isdisjoint(b)```

Output:

`True`

We get `True` as the output since there are no common elements between the sets. Let’s look at another example.

```# create two sets
a = {1,2,3}
b = {2,4,5}
# check if the sets are disjoint
a.isdisjoint(b)```

Output:

`False`

We `False` as the output since element 2 is shared between both sets.
