Fixed most errors, some errors seem to be due to changes to detecting the indentation.

A few questions:

1. Why did you commit .DSStore? Could you remove this please?
2. Why did you create a whole new directory of tests when there already exists a directory of tests? Could you consolidate them?
3. Why did you push so much unnecessary history? Could you rebase a bunch of these commits out?
4. Why did you choose a bug to fix that had not been previously triaged by the maintainers?

1. This is my bad, I've removed it
2. We separated our tests out initially, they have now been moved to the E11.py test file
3. I wasn't aware of the rebase functionality, I've tried rebasing it but not sure if it's at the correct commit right now.

Forgive us for our lack of knowledge, we're all very new with contributing to open source projects

and 4. This was for a university project, with submitting a pull request being part of the requirement.

As there are still some issues, it may be better to hold off on this pull until they're all taken into account. Maybe creating a new issue with specific requirements will help figure out what needs to be updated.
