Python Tuple
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 for Python Tuple
In Python, a tuple is defined using parenthesis. The elements are defined inside parenthesis and are comma separated.
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)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])Output
52
24Python 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) )Output
4Iterate 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)Output
14
52
17
24Or 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 + 1Output
14
52
17

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