 # Python | Convert a list of strings to a list of tuples

Method # 1: Using ` map () + split () + tuple () `

This task can be achieved with a combination of these functions … The ` map ` function can be used to associate logic with each line, the ` split ` function is used to split the inner contents of a list into various attributes of a tuple, and the tuple function performs the task of forming a tuple.

``` # Python3 demo code # convert a list of strings to a list of tuples # Using map () + split () + tuple ()   # initializing list test_list = [ `4, 1` , ` 3 , 2` , `5, 3` ]   # print original list print ( "The original list:" + str (test_list))   # using map () + split () + tuple () # convert a list of strings to a list of tuples res = [ tuple ( map ( int , sub.split ( `,` ))) for sub in test_list]    # print result print ( "The list after conversion to tuple list : " + str (res)) ```

` ` Output:

` The original list: [`4, 1 `,` 3, 2`, `5, 3`] The list after conversion to tuple list: [(4, 1), (3, 2), (5, 3)] `

Method # 2: Using ` map () ` + eval
This is the most elegant way to accomplish this particular task. Where the display function is used to extend the function`s logic to the entire list, the eval function internally performs interconversion and splitting.

 ` # Python3 demo code ` ` # convert a list of strings to a list of tuples ` ` # Using map () + eval `   ` # initializing list ` ` test_list ` ` = ` ` [` ` `4, 1` ` `, ` `` 3, 2` ` `, ` ` `5, 3 `` `] ` ` `  ` # print original list ` ` print ` ` (` `" The original list: "` ` + ` ` str ` ` (test_list)) ` `   # using the () + eval map # convert a list of strings to a list of tuples ```` res = list ( map ( eval , test_list))    # print result print ( "The list after conversion to tuple list: " + str  (res)) ```

Output:

` The original list: [`4, 1`,` 3, 2`, `5, 3`] The list after conversion to tuple list: [(4, 1), (3, 2), (5, 3) ] `
