mpg is a method, so call it:
p.mpg()
If you want to have p.mpg returning the value, you could use a
property:
def _get_mpg(self):
return self.mp/self.gp
mpg = property(_get_mpg)
There isn't anything special about models.py in this regard, this is
just standard Python. So, I suggest learning a little more about
Python. If you go through trial-error learning here you are in for a
long ride.
