__call__方法和可调用对象

定义了call方法的对象，称为可调用对象，即该对象可以像函数一样调用

a = 30

b = 50

c = a+b   ===>c = a.__add__(b)

obj() ====>__call__

 1 class SalaryAcount:
 2     def __call__(self, salary):
 3         yearSalary = salary*12
 4         MouthSalary = salary
 5         daySalary = salary//22.7
 6         hourSalary = daySalary//8
 7 
 8         return dict(yearSalary=yearSalary,MouthSalary=salary,daySalary=daySalary,hourSalary=hourSalary)
 9 
10 s = SalaryAcount()
11 print(s(30000))
