Python 3.4 List manipulation

Hi, I have a list which contains  unique and identical sub lists randomly dispersed across the list . There is no limit on the number of identical sub lists which may exist, and they are not necessarily clustered together.

All sub lists have 1 as their first element - which acts as a counter. So, if there are, 3 identical sub lists [1,9,12] - these three sub lists  would be  replaced by a single sub list [3,9,12]

example

MYLIST = [ [1,9,12], [1, 6, 12],  [1, 5, 5],  [1, 8, 32],  [1, 5, 5],  [1,9,12],  [1,9,12] ]  

MYLIST_Converted =  [[3,9,12], [1, 6, 12],  [2, 5, 5], [1, 8, 32]]

Can someone give me a sense of how best to approach this. Been trying for a couple of days without success.

Thanks.
