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，我們正在實現Properties 。 Python 通過使用屬性@property提供了一種更好的方法，可以借助屬性來實現setter和getter 。 默認情況下，屬性是getters，因此我們必須顯式聲明setter部分。

程序：

class Employee:
def __init__(self): #Constructor
self.__id = 0
self.__name = ""
self.__gender = ""
self.__city = ""
self.__salary = 0
@property
def id(self):
return self.__id
@id.setter
def id(self,value):
self.__id=value
@property
def name(self):
return self.__name
@name.setter
def name(self, value):
self.__name = value
@property
def gender(self):
return self.__gender
@gender.setter
def gender(self, value):
self.__gender = value
@property
def city(self):
return self.__city
@city.setter
def city(self, value):
self.__city = value
@property
def salary(self):
return self.__salary
@salary.setter
def salary(self, value):
self.__salary = value
def 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=i
e.name=n
e.gender=g
e.city=c
e.salary=s
id2 = e.id
name2 = e.name
gender2 = e.gender
city2 = e.city
salary2 = e.salary
print("\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()

Output

輸出量

Enter Employee Data:
Enter Id        :101
Enter Name      :Amit
Enter Gender:Male
Enter City      :Gwalior
Enter Salary:35000
Displaying Employee Data:
Id              : 101
Name    : Amit
Gender  : Male
City    : Gwalior
Salary  : 35000
