Roman numbers to numerical converter using python

By katari.jakariya

A Python converter that translates Roman numerals into their corresponding numerical values efficiently and accurately.

The Roman numeral system is an ancient numeric representation that uses combinations of letters to represent values. To convert these Roman numerals into their numerical equivalents, a Python program can be designed to handle the conversion process.

The converter would typically take a Roman numeral string as input and apply a set of rules to calculate the corresponding numerical value. One possible approach is to iterate through the Roman numeral string from left to right, comparing each character to its adjacent characters.

Based on the comparison, the program would determine whether to add or subtract the corresponding value from the total. For example, if a character represents a smaller value than the next character, subtraction is performed, whereas addition is used in all other cases.

The program would keep track of the total value as it iterates through the string, updating it accordingly. At the end of the iteration, the program would return the calculated numerical value.

To handle the different Roman numeral symbols and their corresponding values, a lookup table or dictionary could be employed. This table would map each Roman numeral character to its respective numerical value. This allows the program to easily retrieve the value associated with each character during the conversion process.

Additionally, the program would incorporate error handling to detect and handle invalid inputs. For instance, if the input string contains an invalid Roman numeral sequence or an unrecognized character, an appropriate error message would be displayed.
