Python convert formatted string to list

I have a string "[u'foo']" (Yes, it includes the square brackets and the u''). I have to convert开发者_如何学C that to a list which looks like [u'foo'].

list("[u'foo']") won't work.

Any suggestions?

>>> import ast
>>> s = "[u'foo']"
>>> ast.literal_eval(s)
[u'foo']

documentation

eval("[u'foo']", {'__builtins__':[]}, {})
