 # 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`] `
