Tuples in Python

Last Updated : December 11, 2025

What Are Python Tuples?

Tuples in Python are a collection of elements in a round bracket() or not but separated by commas. Tuples are similar to list in some operations like indexing, concatenation, etc. but lists are mutable whereas tuples are immutable acts like a string. In Python, Tuples are converted into lists by using the keyword list and list are converted into tuples by using keyword "tuple".

Here we will see some examples to understand how to create tuples?, convert lists into tuples?, concatenation of tuples, nested tuples, etc.

Creating Tuples

In Python, a tuple is an immutable collection of items, which means its elements cannot be changed once defined. Tuples can hold different types of data and are created by placing comma-separated values inside parentheses. You can also create an empty tuple or a tuple with a single element by using specific syntax.

Example

In the following example, we are creating different types of tuples: a normal tuple, a tuple with multiple elements, an empty tuple, and a tuple with a single element. We then print each tuple to see the output.

t='Python','Tuple','Lists'
t2=('Python','Tuple','Lists','Includehelp','best')

e_t=()

u_l_t=('includehelp',)

print('empty tuple:',e_t)
print('Unit length tuple:',u_l_t)
print('first tuple:',t)
print('Second tuple:',t2)

Note: When you are going to create a tuple of length 1 in Python then you must put a comma after the element before closing the round brackets.

Output

empty tuple: ()
Unit length tuple: ('includehelp',)
first tuple: ('Python', 'Tuple', 'Lists')
Second tuple: ('Python', 'Tuple', 'Lists', 'Includehelp', 'best')

Here, we have seen that if we are creating tuples with round brackets or not both results are the same.

Concatenation of Tuples

We can simply add tuples like lists by using plus (+) sign between it. Let's suppose the same tuples that we have created just above and try to add these tuples.

Example

In the following example, we are combining two tuples into one using the + operator and printing the result.

t  = 'Python','Tuple','Lists'
t2 = ('Python','Tuple','Lists','Includehelp','best')

print('Concatenation of Tuples:\n',t+t2)

Output

Concatenation of Tuples: 
('Python', 'Tuple', 'Lists', 'Python', 'Tuple', 'Lists', 'Includehelp', 'best')

Converting Between Lists and Tuples

In Python, you can easily convert between lists and tuples using built-in functions.

• Convert a list into a tuple: Use the tuple() function and pass the list as an argument.
• Convert a tuple into a list: Use the list() function and pass the tuple as an argument.

This allows you to switch between mutable lists and immutable tuples depending on your needs.

Example

In the following example, we are converting a tuple into a list using the list() function and then converting that list back into a tuple using the tuple() function. The results are printed to show both conversions.

t=('Python','Tuple','Lists','Includehelp','best')

l=list(t) #now l is list.
t2=tuple(l) #Here list is converted into tuple.

print('tuple is converted into list:',t)
print('list is converted into tuple:',t2)

Output

tuple is converted into list: ['Python', 'Tuple', 'Lists', 'Includehelp', 'best']
list is converted into tuple: ('Python','Tuple','Lists','Includehelp','best')

Nested Tuples

Nested tuples means one tuple inside another like nested lists. To create a nested tuple, we have to simply put both or more tuples in the round brackets separated with commas. Again we will assume the same tuple that we have created above and try to make it in the form of a nested tuple. Let's look at the program,

Example

In the following example, we are creating a nested tuple by combining two existing tuples into a single tuple. The nested tuple is then printed to show its structure.

t='Python','Tuple','Lists'
t2=('Python','Tuple','Lists','Includehelp','best')

nested_t=(t,t2)

print('Nested tuple:',nested_t)

Output

Nested tuple: (('Python', 'Tuple', 'Lists'), ('Python', 'Tuple', 'Lists', 'Includehelp', 'best'))
