sounds like you want ast.literal_eval():

  Python 2.7.3 (default, Jan  2 2013, 13:56:14) 
  [GCC 4.7.2] on linux2
  Type "help", "copyright", "credits" or "license" for more
  information.
  >>> s = "[{'a':1, 'b':2}, [1,2,3], 10]"
  >>> import ast
  >>> print repr(ast.literal_eval(s))
  [{'a': 1, 'b': 2}, [1, 2, 3], 10]
