Thanks for your comments, Mark. I understand it now. The list(escape codes): ['\xd6\xd0\xce\xc4','\xd6\xd0\xce\xc4','\xd6\xd0\xce\xc4'] is from a postgresql database with "select" statement.I will postgresql database configurations and see if it is possible to return ['中文','中 文','中文'] directly with "select" statement. ouyang -- http://mail.python.org/mailman/listinfo/python-list
