我希望字典按发现日期的顺序排列，因此字典按日期排序。我查看了this python site，但是代码无法正常工作，尝试使用此类时出错。任何想法为什么以及如何解决？
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>')

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
如何不定义其参数？
我希望将其作为{date:link，date:link}的字典，但可以按可变页面中日期的顺序排列。我希望顺序与变量页面中的日期相同，因此2013年8月25日:链接，2013年9月1日:链接，
我想将其保存在字典中，因为我将其粘贴到了javascript网站中，因此我可以输入日期并获取链接，还可以有序地向下滚动菜单。
最佳答案
如果要使用Python库中的内容，则需要先导入该库:
from collections import OrderedDict, Counter
