Convert Roman numerals to integers in Python using a clean and beginner-friendly approach.
This simple script demonstrates how to implement Roman numeral conversion logic using Python data structures and control flow.
Roman numerals are composed of the following seven symbols:
Symbol | Value |
---|---|
I | 1 |
V | 5 |
X | 10 |
L | 50 |
C | 100 |
D | 500 |
M | 1000 |
- I before V or X (e.g. IV = 4, IX = 9)
- X before L or C (e.g. XL = 40, XC = 90)
- C before D or M (e.g. CD = 400, CM = 900)
- Converts valid Roman numerals (1 - 3999) into integers
- Handles all subtractive cases
- Clean O(n) algorithm
- Beginner-friendly code
- Can be integrated into larger Python projects
# Example usage
if __name__ == "__main__":
converter = Solution()
print(converter.romanToInt("XI")) # Output: 11
