Summary

In Python, Tuple is a collection of items. In Python Tuple, items are ordered, and therefore can be accessed using index.

Also, an important property to note about Python Tuple is that, it is immutable. You cannot change the items of a tuple in Python.

But, if it is really necessary for you to change a tuple, you may convert the tuple to a list, modify it, and convert back to a list. This is only a workaround to modify a tuple.

Examples

A Python Tuple can contain a definite number of items belonging to different datatypes.

Following are some of the examples for Tuples in Python.

tuple1 = (14, 52, 17, 24)
tuple2 = ('Hello', 'Hi', 'Good Morning')
tuple3 = (1, 'Tony', 25)

Run

Create a Tuple

To create a tuple, you can provide the comma separated items enclosed in parenthesis or use tuple() builtin function. tuple() accepts an iterable and converts the iterable into tuple.

In the following program, we will create a tuple in two ways: using parenthesis and tuple() builtin function.

Python Program

tuple1 = ('a', 'e', 'i', 'o', 'u')
tuple2 = tuple(['a', 'e', 'i', 'o', 'u'])

Run

Access Tuple Items using Index

As Tuple items are ordered, you can access them using index as that of items in a Python List.

Python Program

tuple1 = (14, 52, 17, 24)
print(tuple1[1])
print(tuple1[3])

Run

Output

52
24

Python Tuple Length

Like any other collection in Python, you may use len() builtin function to get the length of a tuple.

Python Program

tuple1 = (14, 52, 17, 24)
print( len(tuple1) )

Run

Output

Iterate over items of Python Tuple

You can iterate over Python Tuple’s items using for loop.

Python Program

tuple1 = (14, 52, 17, 24)
for item in tuple1:
    print(item)

Run

Output

Or you can also use while loop with tuple length and index to iterate over tuple’s items.

Python Program

tuple1 = (14, 52, 17, 24)

index = 0
while index<len(tuple1):
    print(tuple1[index])
    index = index + 1

Run

Output

Summary

In this Python Tutorial, we learned what a Tuple is in Python and how to define and access it in different ways.
