Hey, @Anny,

You can try this:

from collections import Counter 

# initializing string 

test_str = "Pythonforall"

# using collections.Counter() to get  

# count of each element in string 

res = Counter(test_str) 

# printing result  

print ("Count of all characters in Pythonforall is :\n "

                                           +  str(res))

Count of all characters in Pythonforall is :
Counter({'o': 2, 'l': 2, 'a': 1, 'f' : 1, 'h': 1, 'n' : 1, 'p': 1, 'r': 1, 't': 1, 'y' : 1})
