2b365284c8 Removed Unnecessary Assignment for 'error' Var (#920)
`error = abs(f(a))` was declared on line 24 and line 32. It is unnecessary to have in both places.
I removed the second instance since it wastes resources to keep redefining the variable inside the for loop.
This fixes an [issue found by lgtm](66c4afbd0f/files/maths/newton_raphson.py)

4fb4cb4fd1 Travis CI: Simplify the testing (#887)
* Travis CI: Simplify the testing

* flake8 . --count --select=E9,F63,F7,F82 --show-source --statistics

* python: 3.7

* dist: xenial for python: 3.7

* Delete .lgtm.yml

These changes were created to get around the fact that Travis CI was not enabled on this repo.  Now that Travis is enabled, we can remove these modifications.

The problems are that:
1. [LGTM does not want us running flake8 on their infrstructure](https://discuss.lgtm.com/t/can-i-get-lgtm-to-run-flake8-tests/1445/6) and
2. when we do, it [does not work as expected](https://discuss.lgtm.com/t/tests-are-not-automatically-run-when-lgtm-yml-is-modified/1446/4).

2333f93323 Change Declaration of Var 'j' to None (#921)

a99acae32d Add docstring and comments per Issue #727 (#895)
I've added comments to make understanding this method a little easier for those that are not familiar.  This should close out #727 .

Other changes:
1. added if __name__ == '__main__' rather than the "# MAIN" comment
2. put in return for distances and vertices.  Previously everything was just printed out, but someone may find it useful to have the algorithm return something.
3. Other PEP8 changes
4.  Added example input and expected output as a check to make sure any future changes will give the same output.
