Question

Create a new Type called Fraction

Fraction when created takes in two values (numerator and denominator, num and den)

should be able to add and subtract two fractions (think common denomenator when adding and subtracting)
Inverting
display the representation of the number as a fraction
here is part of the class Fraction

class Fraction(object):

def _init_(self, num, den):
self.num = num
self.den = den

def _str_(self):
return str(self.num) + "/" + str(self.den)

def _add_(self, other):
pass

def _sub_(self,other):
pass

def inv(self):
pass

def _repr_(self):
return str(self.num) + "/" + str(self.den)

Here is an example of how it should work when using the console:
>> x = Fraction(2,3)
>> print(x)
2/3
>> y= Fraction(3,4)
>> print(y)
3/4
>> z = x + y
>> print(z)
17/12
