Step 1: #importing collections packages to use its functions, specificaly Counter

from collections import Counter

Step 2: using sorted functions this will short the charecters alphabetically before even counting the frequency of each charecters

sort_s = sorted(s)

Step 3: using Counter function from collections package in python to count and pair each character with its frequency

character_counts = Counter(sort_s)

Step 5: printing key and value of dic in Counter but only top 3

for char, count in character_counts.most_common(3):
		print (char, count)
