python count character occurrences

# initializing string  
test_str = "Grepper Answer"
  
# using count() to get count  
# counting e  
counter = test_str.count('e') 
>> 3

# using count() to get count  
# counting e  
counter = test_str.count('e')

# each occurrence frequency using  
# naive method

                                        +  str(all_freq))
