Question

The code below is supposed to supposed to print the answers to different fraction calculations. However when I run it, it prints out nothing. If it is possible please revise the code to make it work as it should. Thank you!

Original code:

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 show(self):
print (self.num),"/",(self.den)

def __str__(self):
return str(self.num)+"/"+str(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 __eq__(self, other):

firstnum = self.num * other.den
secondnum = other.num * self.den

return firstnum == secondnum

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
newden = self.den * otherfraction.den
common = gcd(newnum,newden)

return Fraction(newnum//common, newden//common)

def __truediv__(self, otherfraction):
newnum = self.num * otherfraction.den
newden = self.den * otherfraction.num
common = gcd(newnum, newden)

return Fraction(newnum//common, newden//common)

def __lt__(self, otherfraction):

num1 = self.num * otherfraction.den
num2 = otherfraction.num * otherfraction.num

if num1 < num2:
return True
else:
return False

def main():
x = Fraction(1,2)
y = Fraction(2,3)
print (x + y)
print (x == y)
print (y - x)
print (x * y)
print (y/x)
print (x < y)
