96:__call__()方法和可调用对象

###__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被调用。

# 测试__call__,可调用对象
class SalaryAccount:
    '''工资计算类'''

    def __call__(self, salary):
        yearSalary = salary * 12
        daySalary = salary // 30
        hourSalary = daySalary // 8

        return dict(monthSalary=salary, yearSalary=yearSalary, daySalary=daySalary, hourSalary=hourSalary)


s = SalaryAccount()

print(s(5000))  # 可以像调用函数一样调用对象的__call__方法

输出结果:

D:\work\python\three\venv\Scripts\python.exe D:\work\python\three\mypy08.py 
{'monthSalary': 5000, 'yearSalary': 60000, 'daySalary': 166, 'hourSalary': 20}
