Convert Tuple to Set

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

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

Use set() builtin function.
Unpack Tuple inside curly braces.

1. Convert Tuple to Set using set() builtin function

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

In the following program, we take a tuple with strings, and convert it into a set.

Python Program

#take a tuple of elements
myTuple = ('apple', 'banana', 'cherry')
#convert tuple into set
output = set(myTuple)
print(f'Set : {output}')

Output

Set : {'cherry', 'banana', 'apple'}

If there are any duplicates in the given tuple object, they are ignored. A set can contain only unique elements.

In the following program, we take a tuple of strings where some of the elements are repeated inside the tuple (duplicates), and convert it into a set.

Python Program

#take a tuple of elements
myTuple = ('apple', 'banana', 'cherry', 'banana')
#convert tuple into set
output = set(myTuple)
print(f'Set : {output}')

Output

Set : {'cherry', 'banana', 'apple'}

2. Convert Tuple to Set by unpacking the Tuple inside curly braces

We can also unpack the items of given tuple inside curly braces to create a set.

In the following program, we have a tuple of strings, and we shall unpack the elements of this tuple inside curly braces.

Python Program

#take a tuple of elements
myTuple = ('apple', 'banana', 'cherry', 'banana')
#unpack tuple items and form set
output = {*myTuple}
print(f'Set : {output}')

Output

Set : {'apple', 'banana', 'cherry'}

Summary

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