How to create a set in Python?

Python – Create a Set

To create a set in Python, enclose the elements in curly braces and assign it to a variable. Or you can pass an iterable (list, tuple, etc.) to the set() built-in function to create a set from the elements of the iterable.

Create set using curly braces

In the following program, we create a set of strings using curly braces and assign it to a variable s.

Program

s = {'apple', 'fig', 'banana'}
print(s)

Output

{'fig', 'apple', 'banana'}

Create set using set() builtin function

In the following program, we use set() built-in function to create a set of strings and assign it to a variable s.

Program

s = set(['apple', 'fig', 'banana'])
print(s)

Output

{'fig', 'apple', 'banana'}

Create an empty set

To create an empty set in Python, pass no argument to set() built-in function.

Program

s = set()
print(s)

Output

set()
