How to determine the length of a set in Python

In this tutorial, we are going to learn about how to get the length of a set in Python with the help of examples.

In Python, a set is a collection of unchangeable, unindexed, unordered data. The sets are defined using the currly braces {}.

Consider, we have a following set in our Python code:

usersSet = {"apple", "grapes", "kiwi"}

Using the len() function

To get the length of a set, we can use the len() function in Python.

The len() function takes the set as an argument and returns the number of items in it.

Here is an example:

usersSet = {"apple", "grapes", "kiwi"}
length = len(usersSet)

print(length)

Output:
