クラスから返すメソッド

Question

私はPythonとラーニングクラスの初心者です。私は以下のクラスで方法chargeを返すことに困難を抱えてきました。私は.feeとchargeを使ってみました。

class Job: 

rate = 1.04 


def __init__(self, location, salary, description, fee) : 
    self.location = location 
    self.salary = salary 
    self.description = description 
    self.fee = fee 



def Charge(self): 
    self.fee = int(self.fee + Job.rate) 


job1=Job("london",23000,"Accounts Assistant",1200) 
job2=Job("london",25000,"Accounts Assistant",500) 

job1.rate = 1.05 

job1.charge() 
print(job1.fee) 

Answer 1

多少の書式設定やコメントが参考になるかもしれません。 chargeのケースをChargeメソッド名に正しく設定しました。私はあなたの問題は何

class Job: 

    rate = 1.04 

    def __init__(self, location, salary, description, fee) : 
     self.location = location 
     self.salary = salary 
     self.description = description 
     self.fee = fee 

    def Charge(self): 
     self.fee = int(self.fee + Job.rate) # use class amount 1.04 
    def Charge2(self): 
     self.fee = int(self.fee + self.rate) # use instance (11.05 set below) 

job1 = Job("london",23000,"Accounts Assistant",1200) # create instance 
job2 = Job("london",25000,"Accounts Assistant",500) # create instance 

job1.rate = 11.05 

job1.Charge() # execute, adds 1.04 to 1200, then make int of that 
print(job1.fee) # outputs 1201 
job1.Charge2() # execute, adds 11.05 to 1201, then make int of that 
print(job1.fee) # outputs 1212 
print(job2.fee) # outputs 500 
job1.Charge2() # execute, adds 11.05 to 1212, then make int of that 
print(job1.fee) # outputs 1223 
job1.Charge() # execute, adds 1.04 to 1223, then make int of that 
print(job1.fee) # outputs 1224
