title: Python, specific count of chars in string
body: <p>I am trying to count the number of occurrences in a string in python. I would like to take a binary input, say '001101'. Then count the number of 1s, 0s, 11s, 00s etc.</p>
  
  <p>I have tried to implement this by using count, but this will output that there are 3 1s, when i only want it to output 1 1, and 1 11s and for it to not count them individually, unless they are on their own.</p>
  
  <p>I have also tried to implement this with find, but i am having the same problem.</p>
  
  <p>Any help would be appreciated, thanks.</p>
