IN PYTHON 3: Write a Python program to read the attached text file containing words, count the occurrence of each unique word and store the words in alphabetical order in a text file listing the word and the total count of that word. You cannot use any advanced features such as dictionaries. The program requires user input to determine the name of the file.

(example of the text file that needs to be read = for a brief moment I thought I could hit a 200 Mile Per Hour baseball but baseballs are small and hard to hit)
