Listing objects by date in python 3 : So, i have a list of objects, it looks like this:

ID    Date

1        15/11/2009         
2        11/06/2010        
3        11/09/2015         
4        12/08/2013        
5        09/08/2011        
6     11/10/2012         
7     11/10/2014         


Now, I want to sort that list of objects by its date. I have tried `sorted(list,key=lambda x: datetime.datetime.strptime(x, '%m-%Y'))`, tried `list.sort()`, tried all kind of different things, but it simply doesnt sort.

Can somebody help me?
