   for char in input:
       counts[char] = counts.get(char, 0) + 1

   return list(counts.items())

from collections import OrderedDict, Counter

class OrderedCounter(Counter, OrderedDict):

def abbrevName(name):
    return '.'.join(w[0] for w in name.split()).upper()

abbrevName = lambda name: ".".join(e[0].upper() for e in name.split())

''.lower()
