# Python | Convert list of lists to list of strings

|

Method # 1: Using List Comprehension + `join()`
A combination of the above functions can be used to accomplish this task. In this we are doing the task of iterating using a list comprehension and join () is used to perform the task of joining a string to a list of strings.

 ` # Python3 code to demonstrate how it works ` ` # Convert list of lists to list of strings ` ` # using list comprehension + join () `   ` # initialize the list ` ` test_list ` ` = ` ` [[[` ` "g" ` `, ` ` "f" ` `, ` ` "g" ` `], [` ` "i" ` `, ` ` "s" ` `], [` "b" `, ` ` "e" ` ` , ` ` "s" ` `, ` ` "t" ` `]] `   ` # print the original list ` ` print ` ` (` ` "The original list:" ` ` + ` ` str ` ` (test_list)) `   ` # Convert list of lists to list of strings ` ` # using a list comprehension + join () ` ` res ` ` = ` ` [’’ .join (ele) ` ` for ` ` ele ` ` in ` ` test_list] ` ` `  ` # print result ` ` print ` ` (` ` "The String of list is:" ` ` + ` ` str ` ` (res)) `

Output:

` The original list: [[’g’,’ f’, ’g’], [’ i’, ’s’], [’ b’, ’e’,’ s’, ’t’]] The String of list is: [’ gfg’, ’is’,’ best ’] `

Method # 2: Using ` map () + join () `
The above task can also be done with using a combination of the above methods. In this we accomplish the task of transforming using join and iteration using map ().

 ` # Python3 code to demonstrate how it works ` ` # Convert list of lists to list of strings ` ` # using map () + join () `   ` # initialize the list ` ` test_list ` ` = ` ` [[` ` "g" ` `, ` `" f "` `, ` `" g "` `], [` ` "i" ` `, ` ` "s" ` `], [` ` "b" ` `, ` ` "e" ` `, ` ` "s" ` `, ` ` "t" ` `]] `   ` # print original list ` ` print ` ` (` ` "The original list:" ` ` + ` ` str ` ` (test_list)) `   ` # Convert list of lists to list of strings ` ` # using map () + join () ` ` res ` ` = ` ` list ` ` (` ` map ` ` (’’ .join, test_list)) `   ` # print result ` ` print ` ` (` ` "The String of list is: "` ` + ` ` str ` ` (res)) `

Output:

` The original list: [[ ’g’,’ f’, ’g’], [’ i’, ’s’], [’ b’, ’e’,’ s’, ’t’]] The String of list is: [’ gfg ’,’ is’, ’best’] `
