Convert String to Set in Python

Last Updated : 19 Feb, 2025

There are multiple ways of converting a String to a Set in python, here are some of the methods.

Using set()

The easiest way of converting a string to a set is by using the set() function.

Example 1 :

Python

s = "Geeks"

print(type(s))
print(s)

# Convert String to Set
set_s = set(s)

print(type(set_s))
print(set_s)

Output

<class 'str'>
Geeks
<class 'set'>
{'s', 'e', 'k', 'G'}

Let's explore other methods of converting string to set:

Using set() with split() method (for words)
Using dict.fromkeys()

Using set() with split() method (for words)

To convert words from a sentence into a set, use spilt() method before set().

Example:

Python

s = "Geek for Geeks"

# split the string and then convert it to set
set_words = set(s.split())
print(set_words)

Output

{'for', 'Geeks', 'Geek'}

Using dict.fromkeys()

We can also convert a string to a set by using dict.fromkeys() as it creates a dictionary from an iterable and sets the values to none for every key.

Example:

Python

# create a string
s = "developer"

set_s = set(dict.fromkeys(s))
print(set_s)

Output

{'l', 'v', 'o', 'd', 'e', 'p', 'r'}
