Question

How to reducing fraction using class in Python

Answer 1

class GetFraction(object):

    def __init__(self, number, denominator):
        self.numerator, self.denominator = GetFraction.reduce(number, denominator)

    @staticmethod
    def gcd(number, denominator):
        while denominator != 0:
            number, denominator = denominator, number % denominator
        return number

    @classmethod
    def reduce(cls, number, denominator):
        gcd_ = cls.gcd(number, denominator)
        return number // gcd_, denominator // gcd_

    def __str__(self):
        return str(self.numerator)+'/'+str(self.denominator)


x = GetFraction(7, 21)
print(x)

x = GetFraction(4, 16)
print(x)
