Refactor

Refactoring is a fancy word for improving your code's structure without changing its behavior.

There are different kinds of refactoring. Here, we'll split the code in main.py across two smaller modules.

Importing

In Python, each .py file is a module. You can bring functions, variables, and classes from one module into another with an import statement. A module's name is just its filename without the .py extension.

For example, a database.py module might contain a connect function and a db_version variable. You could import both into main.py:

from database import connect, db_version

We'll organize BookBot with this structure:

main.py: The program's entry point and file-reading logic
stats.py: Functions that analyze the text

Assignment

Create a new stats.py file, then move your word-counting function from main.py into stats.py.
Import the function into main.py. For example, if you named it get_num_words, the import should look like this:
```
from stats import get_num_words
```

Run and submit the CLI tests from the root of your project.
