In this project, you'll write a program to calculate and display the number of times each word appears in Life, the Universe and Everything! (or any other book). In the process, you'll get to practice almost all the Python skills you have acquired over the course, including command-line arguments, file input-output, strings and string methods, functions, lists and dictionaries, custom sorting, loops and if-statements. Let's get started! (Sidenote: Life, the Universe and Everything! is the third book in the Hitchhiker's Guide to Galaxy science fiction series by Douglas Adams).
