Convert integers to roman numerals and vice versa

roman_numbers is a simple Python library that lets you convert from python int to roman numerals (represented as a python string) or convert from roman numerals to python int.

To install this script you need setuptools From the command line run

[sudo] python[3] setup.py install

If you want to run test locally you can simply

python[3] test_roman_numbers.py

or, if you have installed pytest, you can run

pytest

Once installed you can simply import this module in the usual way. For a complete function documentation refer to pydoc.

No system to write large roman numeral is currently supported.

Convetion functions are available in two different forms:

• safe: those versions(function name end with _safe) perform checks on the input, ensuring that input type is correct and input variables are in the right form.

• fast: those versions don't perform any check on the input, assuming the values are both of the correct type and in the correct form.

• int_to_roman (integer to roman numeral convertion) consider as correct input any python integer lerger then zero

• roman_to_int (roman numeral to integer convertion) consider as correct input ant python string that contains a correct roman numeral and nothing more. To test if a string is correct or not is_valid_roman function is available
