i need help writing program in python

class Fraction: def __init__(self, top, bottom): self.num = top self.den = bottom def __add__(self, otherFraction): newNum = self.num * otherFraction.den + \ self.den * otherFraction.num newDen = self.den * otherFraction.den common = self.gcd(newNum, newDen) return Fraction(newNum // common, newDen // common) def __eq__(self, other): firstNum = self.num * other.den secondNum = other.num * self.den return firstNum == secondNum def gcd(self, m, n): while m % n != 0: oldm = m oldn = n m = oldn n = oldm % oldn return n def __str__(self): return str(self.num) + "/" + str(self.den)
