Convert Set to List

Sometimes, because of the differences in how elements are stored in a list, or set, we may need to convert a given Set of elements into a List in Python.

In this tutorial, we shall learn how to convert a given set into a list. There are many ways to do that. And we shall discuss the following methods with examples for each.

Use list() builtin function.
Use List Comprehension.

1. Convert Set to List using list() builtin function

list() builtin function can take any iterable as argument, and return a list object formed using the elements from the given iterable.

In the following program, we take a set of strings, and convert it into a list.

Python Program

#take a set of elements
mySet = {'apple', 'banana', 'cherry'}
#convert set into list
output = list(mySet)
print(f'List : {output}')

Output

List : ['apple', 'cherry', 'banana']

2. Convert Set to List using List Comprehension

In the following program ,we use List Comprehension and create a list from the elements of the Set.

Python Program

#take a set of elements
mySet = {'apple', 'banana', 'cherry'}
#create list from elements of set
output = [x for x in mySet]
print(f'List : {output}')

Output

List : ['banana', 'apple', 'cherry']

Summary

In this tutorial of Python Examples, we learned how to convert a Python Set into a List using different methods, with the help of well detailed example programs.
