## Overview
A **set** in Python is used to store multiple unordered and unchangeable items in a single variable. 
A set is written with braces (`{}`).

For example:
```
myset = {"USA", "CANADA", "BRAZIL"}
```
In the code above, the variable `myset` represents the set, while `"USA"`, `"CANADA"`, and `"BRAZIL"` are the **elements** of the set.


## How to determine the length of a set
To determine the length of a set in Python, we use the **`len()` function**.
## Syntax
```
len(set)
```
## Parameters 
The `len()` function takes a single mandatory parameter, which is the set data type.

## Return value 
The `len()` function returns the length of the set passed to it.
## Example


# creating a set
myset = {"USA", "CANADA", "BRAZIL"}

# implementing the len() function
print(len(myset))


## Explanation
* **Line 2**: We create the set `myset`.
* **Line 5**: We use the `len()` function to get  the length of the set and print it.

> Note: The output of the code above, `3`, means that the set contains three elements. It represents the length of the given set.
