首先是错误，一开始是对于输入的特征字符串分析，然后在添加到列表中出了错

'cmp' 好奇怪，python3没有这个函数了么？
[解决办法]
引自"What's new in python 3.0"：
The cmp() function should be treated as gone, and the __cmp__() special method is no longer supported. Use __lt__() for sorting, __eq__() with __hash__(), and other rich comparisons as needed. (If you really need the cmp() functionality, you could use the expression (a > b) - (a < b) as the equivalent for cmp(a, b).)
