self.day = day
self.month = month
self.year = year

def OccursOn(self,year,month,day):

def __repr__(self):
return self.printlist

class OneTime(Appointment):

def OccursOn(self,year,month,day):
if (self.day == day and self.month == month and self.year == year):
super().printlist.append(self)

def __repr__(self):
return Appointment.__repr__(self)

class Daily(Appointment):
def OccursOn(self,year,month,day):
super().printlist.append(self)

def __repr__(self):
return Appointment.__repr__(self)

class Monthly(Appointment):
def OccursOn(self,year,month,day):
if self.day == day:
super().printlist.append(self)

def __repr__(self):
return Appointment.__repr__(self)
#===================================================================================

p1 = OneTime(12,12,12, 'fracture')

p2 = Monthly(12,10,14, 'head ache')

pat = [p1,p2]

for i in pat:
i.OccursOn(12,12,12)

print(Appointment.printlist)

Answer 1

As I can see, you defined the ``printlist´´ variable outside of the __init__ function. So you cannot use it with ``self´´.
