title: count how many ones are in first consecutive repetition in list
body: <p>For example my list is l=[1113213211] and I want the program to print how many "characters" are in first consecutive repetition of ones, I say ones because they are the the first but it can be any number. For example if list is l=[1113213211] I want my program to print: there are 3 ones then 1 three then 1 two then 1 one then 1 three then 1 two then 2 ones. How can I do that in Python3?</p>
  
  <p>P.S. That list I mentioned before can be different. It can be l=[12325228961112333] or something else.</p>
