Code reuse and formatting...

Add an EMPTY file named maths/__init__.py which will make maths a package.

Travis builds failed because it ran on the old defective code (2nd Last commit). How do I trigger a new build?

I restarted at https://travis-ci.org/TheAlgorithms/Python/builds/561450460?utm_source=github_status&utm_medium=notification

If you want to rebuild, you need to make and commit an insignificant change like add or modify a comment. Just mark that commit with "Force a build" so it is clear to your readers.

I think we are really close here. I was able to get the tests to pass locally just by doing touch maths/__init__.py__ and git add __init__.py__. This creates an empty maths/__init__.py__ file which makes maths into a Python package which allows the imports to work. The one downside of this approach is that when you run locally you need to run from in the directory above maths. So you maths/mobius_function.py to run that script and code mobius_function.py to edit that script, etc.

AWESOME!! Thanks for the perseverance.

Merged.
