Python | Convert list of tuples to list of strings
The interconversion between datatypes is quite useful utility and many articles have been written to perform the same. This article discusses the interconversion between a tuple of characters to individual strings. This kind of interconversion is useful in Machine Learning in which we need to give the input to train model in a specific format. Let’s discuss certain ways in which this can be done.
Method #1 : Using list comprehension + join()
The list comprehension performs the task of iterating the entire list of tuples and join function performs the task of aggregating the elements of tuple into a one list.
# Python3 code to demonstrate # conversion of list of tuple to list of list # using list comprehension + join() # initializing list test_list = [('G', 'E', 'E', 'K', 'S'), ('F', 'O', 'R'), ('G', 'E', 'E', 'K', 'S')] # printing the original list print ("The original list is : " + str(test_list)) # using list comprehension + join() # conversion of list of tuple to list of list res = [''.join(i) for i in test_list] # printing result print ("The list after conversion to list of string : " + str(res)) |

Output :
The original list is : [(‘G’, ‘E’, ‘E’, ‘K’, ‘S’), (‘F’, ‘O’, ‘R’), (‘G’, ‘E’, ‘E’, ‘K’, ‘S’)]
The list after conversion to list of string : [‘GEEKS’, ‘FOR’, ‘GEEKS’]
Method #2 : Using map() + join()
The task performed by the list comprehension can be performed by the map function which can perform extension of logic of one tuple to all tuple in list.
# Python3 code to demonstrate # conversion of list of tuple to list of list # using map() + join() # initializing list test_list = [('G', 'E', 'E', 'K', 'S'), ('F', 'O', 'R'), ('G', 'E', 'E', 'K', 'S')] # printing the original list print ("The original list is : " + str(test_list)) # using map() + join() # conversion of list of tuple to list of list res = list(map(''.join, test_list)) # printing result print ("The list after conversion to list of string : " + str(res)) |

The original list is : [(‘G’, ‘E’, ‘E’, ‘K’, ‘S’), (‘F’, ‘O’, ‘R’), (‘G’, ‘E’, ‘E’, ‘K’, ‘S’)]
The list after conversion to list of string : [‘GEEKS’, ‘FOR’, ‘GEEKS’]
