Is there a standard way to get back li, from repr(li) ?
py> eval('[1, 2, 3]')
[1, 2, 3]
eval is like Pandora´s box, all kind of bad things can come from it. Do
not use it with any user-supplied string.
If you can restrict the values to be just constants, there is a "safe
eval" recipe in http://code.activestate.com
Also, the json format is pretty much like Python syntax, and safe (I
think):
py> import json
py> json.dumps([1,'2',3.0])
'[1, "2", 3.0]'
py> json.loads('[1, "2", 3.0]')
[1, u'2', 3.0]
