RomanAlphabet 1.4

安装

$ pip install RomanAlphabet

用法

将整数值表示成罗马数字系统；

:fromromanalphabet.romanalphabetimportRomanAlphabet:rr=RomanAlphabet("4785"):rr.convert_to_roman():'MMMMDCCLXXXV'

或转换成二进制；

...:rr.convert_to_binary():'1001010110001'

数字也可以按如下方式相互相加或相乘；结果可以是三种类型的数字格式；“十进制”、“二进制”或“罗马”；

:RomanAlphabet.addition("roman",1):'I':RomanAlphabet.multiply("roman",1,2,3):'VI':RomanAlphabet.multiply("decimal",1,2,3):6:RomanAlphabet.addition("binary",1,2,3):'110':RomanAlphabet.multiply("decimal",7,4,2,4,2,3):'10101000000'

如果第一个参数不是“十进制”参数中的一个，则将显示以下错误

InvalidInputError:firstinputmustbeoneof'decimal','binary'or'roman'

罗马数字也可以是一个输入，用整数和二进制格式表示。如果有任何错误，那么作为一个例子，输入没有罗马数字，如果给出，那么将显示一个可以理解的错误。
