How can I get the count of how many times a string appears in my list?












1












$begingroup$


I have a list of strings, like so:



{"aa bb", "cc dd", "aa bb", "aa bb", "cc dd", "ww ss", "ss ss", "kk mm"}


I know WordCounts will return the numbers of every single word, but I want to the word group numbers, i.e., "aa bb" 3 times, and "cc dd" 2 times. How can I do this?

          You can try Tally



          lst = {"aa bb", "cc dd", "aa bb", "aa bb", "cc dd", "ww ss", "ss ss",   "kk mm"};
          
Tally[lst]

          As J.M. says in his comment below, Counts will give the same information as an association.



          Counts[data]



          <|"aa bb" -> 3, "cc dd" -> 2, "ww ss" -> 1, "ss ss" -> 1, "kk mm" -> 1|>




          This is equivalent to 



          Rule @@@ Tally[data] // Association
