1.直接添加、修改、刪除、訪問類對象屬性

class Employee (object):empCount = 0 def __init__(self, name, salary) :self.name = nameself.salary = salaryEmployee.empCount += 1 def displayCount(self) : print "total employee ",Employee.empCountdef displayEmployee(self) :print "name :",self.name , ", salary :", self.salaryemp1 = Employee("SR", 10000) emp1.displayCount() emp1.displayEmployee() emp1.salary = 20000 print emp1.salary emp1.age = 25 print emp1.agedel emp1.age Employee.empCount=500print Employee.empCountEmployee.cc="abc"print Employee.ccdel Employee.empCountprint Employee.empCount

2.使用函數(shù)添加、刪除、修改、訪問類對象屬性
