Example:

tuple = ("python", "includehelp", 43, 54.23)

List is a sequence data type. It is mutable as its values in the list can be modified. It is a collection of ordered set of values enclosed in square brackets [].

Example:

list = [3 ,1,  5, 7]

Tuple of lists is a combination of nested collections. In which multiple lists are enclosed inside a tuple.

Example:

listTup = ([4, 1, 8], [9, 0])

Flattening a tuple of list is converting the tuple of lists to a simple tuple containing all individual elements of the lists of the tuple.

Flatten tuple of lists to a tuple

To flatten a tuple of list to a tuple we need to put all the elements of the list in a main tuple container.

Input:
([4, 9, 1], [5 ,6])

Output:
(4, 9, 1, 5, 6)

Method 1:

One method to flatten tuples of a list is by using the sum() method with empty lust which will return all elements of the tuple as individual values in the list. Then we will convert it into a tuple.

Program:

# Python program to flatten a tuple of list to a tuple

# creating the tuple of list and printing values
listTup = ([4, 9, 1], [5 ,6])
print("The tuple of list : " + str(listTup))

# flattening of tuple of list 
flatTup = tuple(sum(listTup, []))

# Printing the flattened tuple 
print("Tuple after flattening : " + str(flatTup))

Output:

The tuple of list : ([4, 9, 1], [5, 6])
Tuple after flattening : (4, 9, 1, 5, 6)

Method 2:

Another method is using a method from Python's itertools library. The chain.from_iterable() method is used to extract single values from the tuple of a list and store them in a collection. Then we will convert this collection to tuple.

Program:

# Python program to flatten a tuple of list to a tuple
from itertools import chain

# creating the tuple of list and printing values
listTup = ([4, 9, 1], [5 ,6])
print("The tuple of list : " + str(listTup))

# flattening of tuple of list 
flatTup = tuple(chain.from_iterable(listTup))

# Printing the flattened tuple 
print("Tuple after flattening : " + str(flatTup))

Output:

The tuple of list : ([4, 9, 1], [5, 6])
Tuple after flattening : (4, 9, 1, 5, 6)
