Before you begin Make a new project for this lab Create sentiment.py Grab the four text files available on Canvas: sentiment.txt A file with a bunch of words and their positivity score test-positive.txt - A file which should be evaluated as positive test-negative.txt - A file which should be evaluated as negative test-neutral.txt - A file which should be evaluated as neutral Look up the following string functions: split, join, strip String functions page in Python - Types page in Python - Dealing with punctuation and white space . Go through the command line and systems arguments page In your if __name_- |__main__' section, write an interface which allows in a user to pass in the name of a file through the command line like this: python sentiment.py some_file.txt If the user fails to pass in a file name, your code should handle the situation without throwing an Exception by printing a message to the console instructing the user to input a file name.
