Converting Roman to Decimal in Python using gnboorse-rom module

To convert Roman numerals to Decimal (integer) format in Python, you can use the gnboorse-rom module, which provides tools for working with Roman numerals. Here's a step-by-step guide on how to do this:

Step 1: Install the gnboorse-rom Module

First, you need to install the gnboorse-rom module. You can do this using pip:

pip install gnboorse-rom

Step 2: Import the Module in Your Python Script

After installing, you can import the necessary function from the module:

from rom.rom import fromRoman

Step 3: Convert Roman Numeral to Decimal

You can now use the fromRoman function to convert a Roman numeral to its decimal equivalent:

roman_numeral = "IX" # Example Roman numeral decimal_number = fromRoman(roman_numeral) print(decimal_number)

This code will convert the Roman numeral "IX" to its decimal equivalent, which is 9.

Complete Example

Putting it all together, here's a simple script that converts a Roman numeral to a decimal:

from rom.rom import fromRoman def convert_roman_to_decimal(roman_numeral): try: return fromRoman(roman_numeral) except ValueError as e: print(f"Error: {e}") roman_numeral = "IX" decimal_number = convert_roman_to_decimal(roman_numeral) if decimal_number is not None: print(f"Roman numeral '{roman_numeral}' is {decimal_number} in decimal.")

This script defines a function convert_roman_to_decimal that takes a Roman numeral as input and returns the decimal equivalent. It also includes error handling to catch any invalid Roman numeral inputs.

Note

  • Make sure that the input Roman numeral is a valid one; otherwise, the fromRoman function may throw an error.
  • The gnboorse-rom module is not a standard Python library, so ensure it's installed in your environment before running the script.
