I'm sure there are slicker ways to do what you want, but this works:
origList = [1,1,1,2,2,3,3,3,3,4,4]
finalList = []
currList = []
lastItem = origList[0]
for item in origList:
if item == lastItem:
currList.append(item)
else:
finalList.append(currList)
lastItem = item
currList = [item]
finalList.append(currList)
print 'original list:', origList
print 'final list: ', finalList
>>>
original list: [1, 1, 1, 2, 2, 3, 3, 3, 3, 4, 4]
final list: [[1, 1, 1], [2, 2], [3, 3, 3, 3], [4, 4]]
