# Python | Concatenate values ​​of a list of strings of a tuple with a string

|

Method # 1: Using List Comprehension + `join()`
A combination of the above functionality can be used to achieve the above task. In this we get a list of characters using a list comprehension and the conversion task is done by ` join () `.

` `

` # Python3 code to demonstrate how it works # Merge Tuple String List of values ​​in string # using list comprehension + join ()   # initialize the list test_list = [([ ’g’ , ’f’ , ’ g’ ], 1 ), ([ ’i’ , ’ s’  ], 2 ), ([ ’b’ , ’ e’ , ’s’ , ’ t’ ], 3 )]   # print the original list print ( "The original list:" + str (test_list))   # Merge Tuple String List of values ​​in string # using list comprehension + join () res =   [’’ .join (i) for i, j in test_list]   # print result print ( "The joined character list tuple element to string is:" + str (res)) `

` ` Output:

The original list: [([’g’, ’f’, ’g’], 1), ([’i’, ’s’], 2), ([’ b ’,’ e ’,’ s’, ’t’], 3)]
The joined character list tuple element to string is: [’gfg’, ’is’,’ best ’]

Method # 2: Using ` map () + join () ` + lambda
The task accomplished by comprehending the list in the above method can be done with map (), and lamb yes function can be used to build logic to achieve this task.

 ` # Python3 code to demonstrate how it works ` ` # Merge Tuple String List of values ​​into a string ` ` # using map () + join () + lambda `   ` # initialize the list ` ` test_list ` ` = ` ` [([` ` ’g’ ` `, ` ` ’f’ ` `, ` `’ g’ ` `], ` ` 1 ` `), ([` `’ i’ ` `, ` ` ’s’ ` `], ` ` 2 ` `), ([` ` ’b’ ` `, ` `’ e’ ` `, ` ` ’s’ ` `, ` ` ’t’ ` `], ` ` 3 ` `)] `   ` # print original list ` ` print ` ` (` ` "The original list:" ` ` + ` ` str ` ` (test_list)) `   ` # Merge Tuple String List of values ​​in a string ` ` # using map () + join () + lambda ` ` res ` ` = ` ` list ( map ( lambda sub: "" .join (sub [ 0 ]), test_list )) ``   # print result print ( "The joined character list tuple element to string is:" + str (res)) `

Output:

The original list: [([’g’ , ’f’, ’g’], 1), ([’i’, ’s’], 2), ([’b’, ’e’, ​​’s’, ’t’], 3)]
The joined character list tuple element to string is: [’gfg’, ’is’, ’best’]
