import time

class myNote(object):
    def __init__(self, myInt):
        self.name = myInt
        self.provided_time = None
        self.mytime = time.time()

#we're going to consider every thing above here imported

#first we assign a property to our imported object
@property
def mytime(self):
        return self.provided_time or self.mytime
myNote.time = mytime

#construct a list of objects
myNotes = [myNote(i) for i in range(10)]

#show the list before mutation
print[note.name for note in myNotes]

#set the provided_time in some of the onjects
for myI in range(10,0,-2):
    print myI-1
    myNotes[myI-1].provided_time = time.time()
    time.sleep(.5)

#sort the list, use a lambda to call the note.time
myNotes.sort(key=lambda note: note.time, reverse=True)

#print the mutated and sorted list
print[note.name for note in myNotes]
