The lambda stands for a one-line function. Return sum(map(lambda x: values, string)) V = 5 must be added, because there are no more symbols left. I = 1 must be subtracted, because the following letter V = 5 is greater. L = 50 must be added, because the following letter I =1 is lower. M = 1000 must be added, because the following letter L = 50 is lower. Otherwise it will be added.įor example, we want to conver the Roman numeral MCMLIV to an Arabic number: M = 1000 must be added, because the following letter C =100 is lower.Ĭ = 100 must be subtracted because the following letter M =1000 is greater. If a value is lower than the following value, it will be subtracted. Roman numerals are read from left to right, as you add or subtract the value of each symbol.
