Convert a List into a Tuple in Python

List and Tuple in Python are classes of data structures. The list is dynamic, whereas the tuple has static characteristics. In this article, we will convert a list into a tuple by using a few methods. Each of these methods is discussed below.

Converting List into Tuple using tuple()

We can convert a list into a tuple using the tuple() function. This function accepts a list as a parameter, converts into a tuple and returns the result.

Example 1

In the following program, we convert a list to a tuple using the tuple() function.

# using tuple() built-in function
list_names=['Meredith', 'Kristen', 'Wright', 'Franklin']

# convert list to tuple
tuple_names= tuple(list_names)

# print the tuple
print(tuple_names)
print(type(tuple_names))

When you run the program, it will show this output -

('Meredith', 'Kristen', 'Wright', 'Franklin')
<class 'tuple'>

Example 2

Here is another example of using the tuple() built-in function to convert a list to a tuple.

# Define a list
my_list = [1, 2, 3]

# Convert list to tuple   
my_tuple = tuple(my_list)

# Print the tuple
print(my_tuple)

After running the program, you will get this result -

(1, 2, 3) 

Converting List toTuple using loops

To convert a List to a Tuple using loops we need to retrieve each element from the list using a for loop to send it as an argument to the tuple() function.

Example

The following is a program to convert a list to a tuple using a loop.

# Define a list
list_names=['Meredith', 'Kristen', 'Wright', 'Franklin']

# Convert list to tuple using a loop
tuple_names = tuple(i for i in list_names)

# Print the tuple
print(tuple_names)
print(type(tuple_names))

This output will be displayed when the program runs -

('Meredith', 'Kristen', 'Wright', 'Franklin')
<class 'tuple'>

Unpack List in Parenthesis

Using the unpack operator, "*" we can unpack the elements of a list within the paranthesis and assign it to a variable.

Example

In this example, we use the unpacking method to convert a list to a tuple.

list_names=['Meredith', 'Kristen', 'Wright', 'Franklin']
tuple_names= (*list_names,)
print(tuple_names)
print(type(tuple_names))

You will see this result after executing the program -

('Meredith', 'Kristen', 'Wright', 'Franklin')
<class 'tuple'>
