Question

我希望字典保持与找到日期的顺序相同，因此字典按日期排序。我看了this python site但是代码不起作用我在尝试使用这个类时遇到错误。任何想法为什么以及如何解决它？

page = str('<OPTION VALUE="08/25/2013" >08/25/2013</OPTION><OPTIONVALUE="09/01/2013">09/01/2013</OPTION><OPTION VALUE="09/08/2013" >09/08/2013</OPTION><OPTION VALUE="09/15/2013" >09/15/2013</OPTION><OPTION VALUE="09/22/2013" >09/22/2013</OPTION><OPTION VALUE="09/29/2013" >09/29/2013</OPTION><OPTION VALUE="10/06/2013" >10/06/2013</OPTION><OPTION VALUE="10/13/2013" >10/13/2013</OPTION><OPTION VALUE="10/20/2013">10/20/2013</OPTION><OPTIONVALUE="10/27/2013">10/27/2013</OPTION><OPTION VALUE="11/03/2013" >11/03/2013</OPTION><OPTION VALUE="11/10/2013" >11/10/2013</OPTION><OPTION VALUE="11/17/2013" >11/17/2013</OPTION><OPTION VALUE="11/24/2013" >11/24/2013</OPTION><OPTION VALUE="12/01/2013" >12/01/2013</OPTION><OPTION VALUE="12/08/2013" >12/08/2013</OPTION><OPTION VALUE="12/15/2013" >12/15/2013</OPTION>OPTION VALUE="12/22/2013" >12/22/2013</OPTION><OPTION VALUE="12/29/2013" >12/29/2013</OPTION><OPTION VALUE="01/05/2014" >01/05/2014</OPTION><OPTION VALUE="01/12/2014" >01/12/2014</OPTION><OPTION VALUE="01/19/2014" >01/19/2014</OPTION><OPTION VALUE="01/26/2014" >01/26/2014</OPTION><OPTION VALUE="02/02/2014" >02/02/2014</OPTION><OPTION VALUE="02/09/2014" >02/09/2014</OPTION><OPTION VALUE="02/16/2014" >02/16/2014</OPTION><OPTION VALUE="02/23/2014" >02/23/2014</OPTION><OPTION VALUE="03/02/2014" >03/02/2014</OPTION><OPTION VALUE="03/09/2014" >03/09/2014</OPTION><OPTION VALUE="03/16/2014" >03/16/2014</OPTION><OPTION VALUE="03/23/2014" >03/23/2014</OPTION><OPTION VALUE="03/30/2014" >03/30/2014</OPTION><OPTION VALUE="04/06/2014" >04/06/2014</OPTION><OPTION VALUE="04/13/2014" >04/13/2014</OPTION><OPTION VALUE="04/20/2014" >04/20/2014</OPTION><OPTION VALUE="04/27/2014" >04/27/2014</OPTION><OPTION VALUE="05/04/2014" >05/04/2014</OPTION><OPTION VALUE="05/11/2014" >05/11/2014</OPTION><OPTION VALUE="05/18/2014" >05/18/2014</OPTION><OPTION VALUE="05/25/2014" >05/25/2014</OPTION><OPTION VALUE="06/01/2014" >06/01/2014</OPTION><OPTION VALUE="06/08/2014" >06/08/2014</OPTION><OPTION VALUE="06/15/2014" >06/15/2014</OPTION>')

    add_twoF = enter_web_link[:3]+"2F"+ enter_web_link[3:]  #00%2F00%0000
    add_twoF_everywhere = add_twoF[:8] +"2F"+add_twoF[8:]
    add_twoF_everywhere = str(add_twoF_everywhere)

def search_13(page):

    starter = len(starter)
    if start_link == -1:
        return None, 0, None

def getalllinks(page):

    while True:

            links[str_date] ='link' +  endoflinkdate
            page = page[end_date:]

    return links



work = getalllinks(page)
print work

class OrderedCounter(Counter, OrderedDict):  #THIS DOES NOT WORK CAUSES ERRORS 
    def __repr__(self):
        return '%s(%r)' % (self.__class__.__name__, OrderedDict(self))
    def __reduce__(self):
        return self.__class__, (OrderedDict(self),)
var1 = OrderedCounter(page,links)
print var1

错误：

 Traceback (most recent call last):
      File "schedule.py", line 43, in <module>
        class OrderedCounter(Counter, OrderedDict):
    NameError: name 'Counter' is not defined

怎么没有定义它的参数？

我想把它作为字典作为{date：link，date：link}我可以得到这个，但它与变量页面中日期的顺序不一样。我希望订单与变量页面中的日期相同，所以08/25/2013：link，09/01/2013：link，

我想将它保存在字典中，因为我将其粘贴到javascript网站中，这样我就可以输入日期并获取链接，并且还有一个有序的向下滚动菜单。

如果要使用Python库中的内容，则需要先导入库：

from collections import OrderedDict, Counter

尝试保持字典顺序时发生错误
