Nested Tuples in Python

Tuples are similar to the list. A tuple contains number of items separated by commas. The only difference between a list and a tuple is that a list is enclosed with [ ] and the items in it can be changed whereas a tuple is enclosed with ( ) and the items in it cannot be changed. The below is an example that describes the tuple creation.

You can refer basic concept of tuples from the following link:

Tuples in Python

In Python there is also a concept called as nested tuples. Nested tuples are the tuples which comprises of group of tuples.

Creating a nested tuple:

Creating a nested tuple is almost similar as creating a tuple. Here, a tuple is considered as one of the elements in a nested tuple.

Accessing elements from Nested tuple

We can access the elements from a nested tuple by using indexing ‘[ ]’. It is illustrated for the same above example.

 Updating a Nested tuple

We cannot update or change the elements once after they created. It is only possible on nested elements which are it-self immutable like lists. It is shown in below example.

 In the above example [3,4,5] is declared as list and is considered as one of the elements in a tuple. Since the lists are mutable so that the elements are updated in such case. Otherwise we cannot update.

Deleting elements in a Nested tuple

We can’t delete an element in a tuple but we can delete an entire tuple using ‘del’ keyword.

Basic operations on nested tuples:

The following are some of the basic operations on tuples.

Iteration with elements in nested tuple

We can iterate through every element in a nested tuple by using for loops. The below example describes the iteration of an element in tuple.

tup=("Cricket","Tennis","Hockey","Football","Badminton")
for sports in tup:
    print(sports)

Output

We can also iterate by passing strings as a parameters. It is shown in below example.

>>> for str in("Hi","VMS","Welcomes","You"):
	print(str)

	
Hi
VMS
Welcomes
You

Example program

1.A python program to find the maximum value of elements in a nested tuple.

def max_value(tup): 
    result = 0
    for element in tup:
        try:
            if element > result:
                result = element
        except:
            if max_value(element) > result:
                result = max_value(element)
    return result
print(max_value((35, (11, 62),((9.1,3,7),(0,2)))))

Output
