Python – Convert List into Tuple

Convert List to Tuple in Python

Sometimes, because of the differences between a List and Tuple, you may need to convert a Python List to a Tuple in your application.

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

• Use tuple() builtin function.
• Unpack List inside parenthesis.

Examples

1. Convert list into tuple using tuple() builtin function

tuple() builtin function can take any iterable as argument, and return a tuple object.

In the following example, we shall take a list of strings, and convert it into a tuple.

# Take a list of elements
list1 = ['apple', 'banana', 'cherry']

# Convert list into tuple
tuple1 = tuple(list1)

print(f'Tuple : {tuple1}')
print(type(tuple1))

Output

Tuple : ('apple', 'banana', 'cherry')
<class 'tuple'>

You may observe in the output that we have printed the type of the variable tuple1, which is <class 'tuple'>.

2. Convert list into tuple by unpacking List inside Parenthesis

We can also unpack the items of List inside parenthesis, to create a tuple.

In the following program, we have a list, and we shall unpack the elements of this list inside parenthesis.

# Take a list of elements
list1 = ['apple', 'banana', 'cherry']

# Unpack list items and form tuple
tuple1 = (*list1,)

print(f'Tuple : {tuple1}')
print(type(tuple1))

Output

Tuple : ('apple', 'banana', 'cherry')
<class 'tuple'>

Summary

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