In Python, we can easily combine sets by adding two sets together. The easiest way to combine sets is to use **|=** in your Python code.

```
a = {0, 1, 2, 3, 4}
b = {4, 5, 6, 7, 8}
a |= b
print(a)
#Output:
{0, 1, 2, 3, 4, 5, 6, 7, 8}
```

You can also use the set **update()** function to combine sets in Python.

```
a = {0, 1, 2, 3, 4}
b = {4, 5, 6, 7, 8}
a.update(b)
print(a)
#Output:
{0, 1, 2, 3, 4, 5, 6, 7, 8}
```

One other way to join two sets together in Python is with the **union()** function.

```
a = {0, 1, 2, 3, 4}
b = {4, 5, 6, 7, 8}
a.union(b)
print(a)
#Output:
{0, 1, 2, 3, 4, 5, 6, 7, 8}
```

In Python, sets are unordered collections of items. When working with sets, it can be useful to add or remove elements from a set, or combine a set with another set.

We can easily combine two sets together in Python.

There are a number of ways to join two sets together in Python, and the easiest way is to use **|=**.

Below is an example in Python of how to join two sets with **|=**

```
a = {0, 1, 2, 3, 4}
b = {4, 5, 6, 7, 8}
a |= b
print(a)
#Output:
{0, 1, 2, 3, 4, 5, 6, 7, 8}
```

## Combining Two Sets in Python with the set **update()** Function

Python has a number of great built-in functions which allow us to work with collections easily. The Python set **update()** function adds items to a set from another set.

With the **update()** function, we can easily combine two sets.

Below is how to use the **update()** function in Python to combine two sets into one set.

```
a = {0, 1, 2, 3, 4}
b = {4, 5, 6, 7, 8}
a.update(b)
print(a)
#Output:
{0, 1, 2, 3, 4, 5, 6, 7, 8}
```

## Joining Two Sets in Python with the set **union()** Function

One final way to get all of the elements of two sets is to take the union of two sets in Python.

We can use the **union()** function to take the union of two sets and join them together into one set.

Below is a simple example in Python of how to use the **union()** function to combine two sets together.

```
a = {0, 1, 2, 3, 4}
b = {4, 5, 6, 7, 8}
a.union(b)
print(a)
#Output:
{0, 1, 2, 3, 4, 5, 6, 7, 8}
```
