Python | 在属性的帮助下实现setter和getter

In this program, we are implementing Properties. Python offers a better way to implement setters and getter with the help of properties by using attribute @property. By default properties are getters so we have to declare setter part explicitly.

在此程序中，我们正在实现Properties 。 Python 通过使用属性@property提供了一种更好的方法，可以借助属性来实现setter和getter 。 默认情况下，属性是getters，因此我们必须显式声明setter部分。

Program:

程序：

class Employee:def __init__(self): #Constructorself.__id = 0self.__name = ""self.__gender = ""self.__city = ""self.__salary = 0@propertydef id(self):return self.__id@id.setterdef id(self,value):self.__id=value@propertydef name(self):return self.__name@name.setterdef name(self, value):self.__name = value@propertydef gender(self):return self.__gender@gender.setterdef gender(self, value):self.__gender = value@propertydef city(self):return self.__city@city.setterdef city(self, value):self.__city = value@propertydef salary(self):return self.__salary@salary.setterdef salary(self, value):self.__salary = valuedef main():print("Enter Employee Data:")i = int(input("Enter Id\t:"))n = input("Enter Name\t:")g = input("Enter Gender:")c = input("Enter City\t:")s = int(input("Enter Salary:"))e=Employee()e.id=ie.name=ne.gender=ge.city=ce.salary=sid2 = e.idname2 = e.namegender2 = e.gendercity2 = e.citysalary2 = e.salaryprint("\nDisplaying Employee Data:")print("Id\t\t:", id2)print("Name\t:", name2)print("Gender\t:", gender2)print("City\t:", city2)print("Salary\t:", salary2)if __name__=="__main__":main()
