Question

Using Python,

Write an app for patients such as patients requiring surgery and patients who are pregnant and relevant functionalities.

Note : It's not a complex app. It is for my fundamental 2 class to understand the inheritance concept. Simpler the better.

class Surgery(Patient):

        self.surgery_date=date

        return Patient.__str__(self)+' and will undergo '+self.surgery_type+' surgery on '+self.surgery_date

class Pregnant(Patient):

    def __str__(self):
        return Patient.__str__(self)+ ' is '+str(self.weeks)+' weeks pregnant and expecting after '+str(self.get_weeks_left())+' weeks.'
    

peter=Surgery('Peter','02/06/2019','William Cambell','Appendectomy','02/10/2019')
print(peter)
peter.set_surgery_date('03/01/2019')
peter.set_surgery_type('Cholecystectomy')
print(peter)

alice=Pregnant('Alice','02/06/2019','Sarah Williams',30)
print(alice)
