 # 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)]
