Question

How to know how many times strings s , t and n appear in each of the following words to have an output like this:

• descriptions: s 2 , t 1 , n 1
• statements s 2 , t 3 , n 1

The words are not known in advance.The first thing came to my mind was to make a dictionary, but for dictionaries we can only have two unknowns, so any hints how to approach it?
Thanks in advance.

from collections import defaultdict
def counter(STRING):
  h=defaultdict(int)
  for i in STRING:
    if i in "stn":
       h[i]+=1
  return h
for s in ['description','statements']:
    k=counter(s)
    print k + " for " + s
