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.

Otherwise, your code should load in the text from the file, extract the list of unique words, and compute the sentiment score using the dictionary from sentiment.txt. It should then print out the word Positive to the console if the file score is > 0, Negative if the file score is < 0, and Neutral otherwise. There should be no other output to the console.

Below is my current code please help me write out the above requirements in python 3.8
