如何根据对象的属性对对象列表进行排序？ - How to sort a list of objects based on an attribute of the objects?

问题：

I've got a list of Python objects that I'd like to sort by an attribute of the objects themselves. 我有一个Python对象列表，我想按对象自己的属性对其进行排序。 The list looks like: 该列表以下所示：

>>> ut
[<Tag: 128>, <Tag: 2008>, <Tag: <>, <Tag: actionscript>, <Tag: addresses>,
 <Tag: aes>, <Tag: ajax> ...]

Each object has a count: 每一个对象都有一个计数：

>>> ut[1].count
1L

I need to sort the list by number of counts descending. 我须要按递减计数对列表进行排序。

I've seen several methods for this, but I'm looking for best practice in Python. 我已经看到了几种方法，可是我正在寻找Python的最佳实践。
