How to get the size of a set in Python

To get the size of a set in Python, you can call the len() function and pass the set as its argument.

set_size = len(set)

print(set_size) # The size of the set

Let’s see a quick example. Suppose you have a Python set defined as follows:

my_set = {1, 2, 5, 6}

To get the size of my_set, call the len() function and assign the result in a variable:

set_size = len(my_set)

print(set_size) # 4

As you can see, the len() function correctly returned the size of my_set, which is 4.
