Refactor list_distances.py for better structure

Refactor to encapsulate logic in main function and improve variable naming.

Great refactoring! The code is much more organized now. I have a few suggestions for improvement:

1. The new main() function encapsulation is a good improvement over the previous script-at-module-level approach.

2. Variable naming is clearer with left_values

3. The if __name__ == "__main__": guard at the end is a good Python practice for making the script importable.

4. Consider adding docstrings to the main() function to document what the script does.

5. The encoding specification in the file read is good for handling non-ASCII characters.

Overall, this is a solid refactoring that improves code readability and maintainability! and right_values instead of list1 and list2.

I'll add some inline comments on specific lines.

Great refactoring! The encapsulation of the logic into a main() function is much cleaner and follows Python best practices. The use of descriptive variable names like left_values and right_values makes the code self-documenting.
