# Python | Convert string tuples to list of tuples

|

Method # 1: Using ` eval () ` + list comprehension
This problem can be easily solved as one liner using the built-in ` eval ( ) ` which does this task of converting a string to a tuple and comprehending a list.

 ` # Python3 code to demonstrate how it works ` ` # Convert string tuples to list of tuples ` ` # use comprehension list + eval () `   ` # Initializing list ` ` test_list ` ` = ` ` [` ` "(’ gfg’, 1) "` `, ` ` "(’ is’, 2) "` `, ` ` "(’ best’, 3) "` `] ` ` `  ` # print the original list ` ` print ` ` (` ` " The original list is: "` ` + ` ` str ` ` (test_list)) `   ` # Convert string tuples to a list of tuples ` ` # use comprehension list + eval () ` ` res ` ` = ` ` [` ` eval ` ` (ele) ` ` for ` ` ele ` ` in ` ` test_list] `   ` # print result ` print ` (` ` "The list tuple after conversion:" ` ` + ` ` str ` ` (res)) `

Output:

` The original list is: ["(’ gfg’, 1) "," (’is ’, 2)", "(’ best’, 3) "] The list tuple after conversion: [(’ gfg’, 1), (’is’, 2), (’ best’, 3)] `

Method # 2: Using ` eval () + map () `
This task can also be accomplished using a combination of the above functions. The task performed by the above list can be accomplished with ` map () ` in this method.

` `

` # Python3 code to demonstrate how it works # Convert string tuples to list of tuples # using map () + eval ()   # Initializing list test_list = [ "(’ gfg’ , 1) " , " (’is’, 2)" , "(’ best’, 3) " ]   # print original list pr int ( "The original list is:" + str (test_list))   # Convert string tuples to list of tuples # using map () + eval () res = list ( map ( eval , test_list))    # print result print ( "The list tuple after conversion:" + str (res)) `

` ` Output:

` The original list is: ["(’ gfg’, 1) "," (’is’, 2)", "(’ best’, 3) "] The list tuple after conversion: [(’ gfg’, 1), (’is’ , 2), (’best’, 3)] `
