How to create a set in Python | Example code

You can create a set by using curly braces {} in Python. Just create a data type and assign the value using placing all the items (elements) inside curly braces {} and separated by a comma for multiple values.

Declare set

my_set = {"e1", "e2", "e2"}

empty_set = set()

Python set can contain any number of items and they may be of different types (integer, float, tuple, string, etc.)

Note: Mutable data types are now allowed in sets.
