If the list will just contain quoted strings that don't themselves contain commas you can do something ad hoc: In [2]: s = "['a','b','c']" In [5]: [ str(item[1:-1]) for item in s[1:-1].split(',') ] Out[5]: ['a', 'b', 'c'] In Python 3 you can use ast.literal_eval(). >>> import ast >>> s = "['a','b','c']" >>> ast.literal_eval(s) ['a', 'b', 'c'] You can use these recipes: http://code.activestate.com/recipes/511473/ http://code.activestate.com/recipes/364469/ Kent
