Flatten tuple list to string

We are given a list of tuples consisting of integer elements wrapped as strings. We need to create a Python program to flatten the tuple list to String.

We will be creating a program that will flatten the tuple and create a string with the flattened elements. In Python, we have multiple methods and ways to perform this task.

Method 1:

One method to solve the problem is by iterating over each element of the tuple list and creating a new string with all elements joined using the join() method. The iteration is done using list comprehension.

# Python program to flatten tuple list 
# to string using join() 

# Initializing and printing 
# list of tuples
tupList = [('5', '6') ,('1', '8')]
print("The elements of Tuple list are " + str(tupList))

# Flattening Tuple List to String
flatStr = ' '.join([idx for tup in tupList for idx in tup])
print("String consisting of elements of Tuple : " + flatStr)

Output:

The elements of Tuple list are [('5', '6'), ('1', '8')]
String consisting of elements of Tuple : 5 6 1 8

Method 2:

We can use the chain() method from itertools library instead of the list comprehension to iterate elements for concatenation.

# Python Program to flatten Tuple Lists 
# to String using join() and chain() 
# methods

import itertools

# Initializing and printing list of tuples
tupList = [('5', '6') ,('1', '8')]
print("The elements of Tuple list are " + str(tupList))

# Flattening Tuple List to String
flatStr = ' '.join(itertools.chain(*tupList))
print("String consisting of elements of Tuple : " + flatStr)

Output:

The elements of Tuple list are [('5', '6'), ('1', '8')]
String consisting of elements of Tuple : 5 6 1 8
