The easiest -- and most dangerous -- way is
 >>> eval('["aaaa","bbbb","ccc"]')
['aaaa', 'bbbb', 'ccc']

But DO NOT eval unexamined strings from untrusted sources. The reason is =

that it is much the same as letting an untrusted person sit unsupervised =

as the keyboard of your computer with a command window open. You would=20
not want to eval
   "from os import system; system('<command to delete files>')"
where '<command...>' is replaced by something obnoxious for your=20
operating system.
