Using eval() in this case is lame and unsafe:
>>> eval('[__import__("os").system("touch /tmp/foo;ls -l /tmp/foo;echo \'=
Th15 b0x 15 0wn3D\'")]')
-rw-r--r--    1 bo       users           0 Sep 18 10:18 /tmp/foo
Th15 b0x 15 0wn3D

Sure! Why you need to save list as string? You can store as:
 - string with some special separator, e.g.:

=09import random
=09self.separator =3D '_%s_' % random.randint(0xfff, 0xfffff)

=09...

=09addThisToDB =3D self.separator.join(yourList)

   Then:

=09for item in gotBigStringFromDB.split(self.separator):=20
=09=09self.doSomethingWith(item)

 - Make a one more relative table and have less traffic.

--=20
