Write a python program to find the number of occurrences of each word in a text file. The first part of the task is to open the file, then create a dictionary to read each word from the file and compute the word's frequency (consider words written in capital letters equal words written in lower case). At the end build two lists, one with each word in the file (call it words_list) and a second list with the number of occurrences of the word in the file (call it words_count). Do not make distinction among words with capital letters

Building a histogram. Write a python program to find the number of occurrences of each word in a text file. The first part of the task is to open the file, then create a dictionary to read each word from the file and compute the word's frequency (consider words written in capital letters equal words written in lower case).
