Hello All, I need to do the following assignment. I need to know how do i hard code an example for each of the operators I am implementing? What i have so far is below? He said he does not care if we plug in some numbers or if we have user input numbers, however I am unsure of how to write a program that tests each operator? Or can i write one that tests all of them? I don’t know where to start with this. Please help!
We discussed implementing different operators in our Fraction class. Here is a link to some operators in Python (look at Section 10.3.1). https://docs.python.org/3/library/operator.html You may implement as many of these operators as you like (such as isub, itruediv, etc.) You MUST indicate in your header information which operators you are implementing, and you MUST hard code an example for each. def gcd(m, n): while m % n != 0: oldm = m oldn = n m = oldn n = oldm % oldn return n class Fraction: def __init__(self, top, bottom): self.num = top self.den = bottom def __str__(self): if self.den == 1: return str(self.num) elif self.num == 0: return str(0) else: return str(self.num) + "/" + str(self.den) def simplify(self): common = gcd(self.num, self.den) self.num = self.num // common self.den = self.den // common` def show(self): print(self.num, "/", self.den) def __add__(self, otherfraction): newnum = self.num * otherfraction.den + \ self.den * otherfraction.num newden = self.den * otherfraction.den common = gcd(newnum, newden) return Fraction(newnum // common, newden // common) def __sub__(self, otherfraction): newnum = self.num * otherfraction.den - \ self.den * otherfraction.num newden = self.den * otherfraction.den common = gcd(newnum, newden) return Fraction(newnum // common, newden // common) def __mul__(self, otherfraction): newnum = self.num * otherfraction.num * \ self.den * otherfraction.den newden = self.den * otherfraction.den common = gcd(newnum, newden) return Fraction(newnum // common, newden // common) def __imul__(self, otherfraction): if isinstance(otherfraction): return self__mul__(otherfraction) def __iadd__(self, otherfraction): if isinstance(otherfraction): return self__iadd__(otherfraction) def __truediv__(self, otherfraction): newnum = self.num * otherfraction.num // self.den * otherfraction.den newden = self.den * otherfraction.den common = gcd(newnum, newden) return Fraction(newnum // common, newden // common) def __radd__(self, otherfraction): newnum = self.num * otherfraction.num // self.den * otherfraction.den newden = self.den * otherfraction.den common = gcd(newnum, newden) return Fraction(newnum // common, newden // common) def getNum(self): return self.num def getDen(self): return self.den def __gt__(self, otherfraction): return (self.num / self.den) > (otherfraction.num / otherfraction.den) _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
