Python class homework - the method of the subclass is merged into the parent class

Class A is staff, Class B is sales, Class C is hourly workers

class Employee:
def init(self, id, name):
self.id = id
self.name = name

def getselary(self, who):
    if who.Class == "A":
        return who.basic + who.banus - who.offdays*5
    if who.Class == "B":
        return who.basic + who.salesnum * 0.05
    if who.Class == "C":
        return who.workhours * 30

class Clerk(Employee):
Class = “A”

def __init__(self, id, name, basic, banus, offdays):
    super().__init__(id, name)
    self.basic = basic
    self.banus = banus
    self.offdays = offdays

# def getselary(self):
#     return self.basic + self.banus - self.offdays*5

class Saleman(Employee):
Class = “B”

def __init__(self, id, name, basic, salesnum):
    super().__init__(id, name)
    self.basic = basic
    self.salesnum = salesnum

# def getselary(self):
#     return self.basic + self.salesnum * 0.05

class HourlyWorker(Employee):
Class = “C”

def __init__(self, id, name, workhours):
    super().__init__(id, name)
    self.workhours = workhours

# def getselary(self):
#     return self.workhours*30

if name == ‘main’:
clerk = Clerk(“01”, “fuhao”, 3000, 2000, 3)
print(clerk.getselary(clerk))
