This program takes two Roman numerals as arguments and returns their sum as a new Roman numeral.

This program requires:

• pip (to handle the installation)
• pytest (only for testing) This program is tested and compatible with Python 2.7, and Python 3.0-3.6. Users interested in testing should refer to the 'For Developers' section.

When at the root of the project (roman_add/), run:

pip install .

And you're done!

The generic syntax is:

add_roman.py [-h] numeral_a numeral_b

So, for example:

add_roman.py IV V

Would return

add_roman.py IX

IMPORTANT: The numbers must be positive, in all capitals, and in the substractive Roman style (e.g. 4 is expressed IV instead of IIII). Numbers larger than 3999 are forced to use the additive syntax for thousands, e.g. MMMMMX for 5010.

This information can be accessed with:

add_roman.py -h

The testing for this project uses pytest. To run the tests, first install pytest if you haven't already:

pip install pytest

Then navigate to roman_add/roman_add/tests/ and run:

pytest

This will run all unit tests in sequence, and finally functional tests.

Linting was performed with Pyflakes.
