我有一个Python对象列表,我想根据对象本身的属性进行排序.该列表如下:

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

每个对象都有一个计数:

>>> ut[1].count
1L

我需要按递减计数的数量对列表进行排序.

我已经看过几种方法,但我正在寻找Python的最佳实践.

我有一个dicts列表:

b = [{u'TOT_PTS_Misc': u'Utley, Alex', u'Total_Points': 96.0},
 {u'TOT_PTS_Misc': u'Russo, Brandon', u'Total_Points': 96.0},
 {u'TOT_PTS_Misc': u'Chappell, Justin', u'Total_Points': 96.0},
 {u'TOT_PTS_Misc': u'Foster, Toney', u'Total_Points': 80.0},
 {u'TOT_PTS_Misc': u'Lawson, Roman', u'Total_Points': 80.0},
 {u'TOT_PTS_Misc': u'Lempke, Sam', u'Total_Points': 80.0},
 {u'TOT_PTS_Misc': u'Gnezda, Alex', u'Total_Points': 78.0},
 {u'TOT_PTS_Misc': u'Kirks, Damien', u'Total_Points': 78.0},
 {u'TOT_PTS_Misc': u'Worden, Tom', u'Total_Points': 78.0},
 {u'TOT_PTS_Misc': u'Korecz, Mike', u'Total_Points': 78.0},
 {u'TOT_PTS_Misc': u'Swartz, Brian', u'Total_Points': 66.0},
 {u'TOT_PTS_Misc': u'Burgess, Randy', u'Total_Points': 66.0},
 {u'TOT_PTS_Misc': u'Smugala, Ryan', u'Total_Points': 66.0},
 {u'TOT_PTS_Misc': u'Harmon, Gary', u'Total_Points': 66.0},
 {u'TOT_PTS_Misc': u'Blasinsky, Scott', u'Total_Points': 60.0},
 {u'TOT_PTS_Misc': u'Carter …

我想知道用两个键对元组列表进行排序的Pythonic方法是什么,其中用一个(并且只有一个)键进行排序将是相反的顺序,而用另一个键进行排序将不区分大小写.更具体地说,我有一个包含元组的列表:

myList = [(ele1A, ele2A),(ele1B, ele2B),(ele1C, ele2C)]

我可以使用以下代码用两个键对其进行排序:

sortedList = sorted(myList, key = lambda y: (y[0].lower(), y[1]))

要按相反顺序排序,我可以使用

sortedList = sorted(myList, key = lambda y: (y[0].lower(), y[1]), reverse = True)

但这会按两个键的相反顺序排序.

任何提示都非常感谢.
