Added comments to the algerian.py (#401)

* Added comments to the algerian.py

* Update algerian.py

I made changes to the code so that it would pass flake8.

* Update algerian.py

I have revised the comments to comply with Flake8 standards.

* Update algerian.py

I have removed the trailing spaces to ensure AppVeyor passes successfully.
