Python Tuples

Python Tuple is a collection of items.

Python Tuple is Ordered

Items in a Tuple are stored in an order. Therefore, we can access items in a Tuple based on index.

Python Tuple is Immutable

We cannot modify a Tuple. In other words, we cannot add items to a Tuple, cannot update items of a Tuple using index, or cannot remove items from a Tuple.

Create Python Tuple

To create a Tuple in Python, use parenthesis () as shown in the following example.

tuple_1 = (item_1, item_2, item_3)

Place as many items as required inside curly braces and assign it to a variable.

We can also use tuple() builtin function to create a Python Tuple. Pass an iterable to tuple() function, and it returns a Tuple created from the items in that iterable.

tuple_1 = tuple(iterable)

Example

In the following program, we create two tuples: tuple_1 and tuple_2 using parenthesis and tuple() function respectively.

Python Program

#create tuple using parenthesis
tuple_1 = (2, 4, 6)
print(tuple_1)

#create tuple using tuple() builtin function
x = ['a', 'b', 'c']
tuple_2 = tuple(x)
print(tuple_2)

Try Online

Output

(2, 4, 6)
('a', 'b', 'c')

Access Items of Python Tuple

Python Tuple is ordered and an iterable. Therefore, we can access items using index, and iterate over items using for loop or while loop.

Example – Access using Index

In the following program, we create a tuple with three items, and print items one at a time by accessing them using index.

Python Program

tuple_1 = (2, 4, 6)
print(tuple_1[0])
print(tuple_1[1])
print(tuple_1[2])

Try Online

Output

2
4
6

Example – Access using For Loop

In the following program, we create a tuple with three items, and print items one at a time by accessing them using for loop.

Python Program

tuple_1 = (2, 4, 6)

for item in tuple_1:
    print(item)

Try Online

Output

2
4
6
