Python Tuple - Define, Access, Iterate

Python Tuple ? Define, Access, Iterate

Python Tuple

Python Tuple is a collection of elements where elements can be accessed using index and are unchangeable. What does this mean? A tuple can be defined with a definite number of elements that belong to different datatypes. Each member can be accessed using the index. index starts with 0 for the first element and increments for the subsequent elements. You cannot modify a tuple, hence unchangeable.

How to define Python Tuple?

To define a Python Tuple, use parenthesis () , and the elements inside these parenthesis separated by comma. For example (14, "Raghu") is a Tuple. tuple1 = (14, 'Raghu')

You can access the first element using index as tuple1[0] and the second element as tuple1[1] .

Example 1: Basic Python Tuple

In the following example, we define a tuple with an integer and string. Also, we will access the individual elements using index. example.py myTuple = (14, 'Raghu') print(myTuple[0]) print(myTuple[1])

Output 14 Raghu

Example 2: Python Tuples are unchangeable

In the following example, we define a tuple with an integer and string.

We will try to change the elements of this tuple. example.py

myTuple = (14, 'Raghu') myTuple[0] = 25 myTuple[1] = 'Tim'

Output

Traceback (most recent call last): File "example1.py", line 3, in myTuple[0] = 25

TypeError: 'tuple' object does not support item assignment

Yeah. Python Tuple does not support item assignment and hence unchangeable.

Example 3: Iterate over Tuple

In the following example, we define a tuple with an integer and string. We will try to iterate over the elements of this tuple. example.py

myTuple = (14, 'Raghu') for element in myTuple:

print(element)

Output

14 Raghu

In this Python Tutorial, we learned what a Python Tuple is, how to define a tuple, how to access the elements of a tuple and how to iterate over tuple.
