main.py and main_counter.py are almost identical, the difference is that main.py uses some dictionaries and increment oprators to count the number of letters where as main_counter.py uses the Counter which has the same purpose and exisists in collections library. You can specify in run.py which one you want to use. just import the one that you want in run.py and then run it to see the results.
Surprisingly, main.py works faster!
If you want to save the results as an image, you can also specify the name of the image as an optional argument to the LetterFrequency class in run.py
