The following function open_file() opens a file called 'example.txt' and returns the file pointer. This function is called within main and the file pointer is used to read lines in the file. Create a dictionary called 'dict_of_words' that have words as 'keys' and (integar) counters as values. The counter values keep a count of the number of times a word has appeared in the text file. In the end, store the dictionary key,values in a list, sort and print the list on the screen.

Note that the counts are not case-sensitive, that is, 'Word' is the same as 'word' or 'wORd'.

Also, note that your progrom should account for if a ',' (comma) separates two words, e.g. 'food, water, electricity'

Example:

Contents of input text file:

def main(): dictlist = [] fp = open_file() #loop to iterate over lines in file for key, value in dict_of_words.items(): temp = (key,value) dictlist.append(temp) print(sorted(dictlist)) main()
