创建

# 默认: Employee(object)
class Employee:
   empCount = 0
 
   # 构造方法 self 代表类的实例
   def __init__(self, name):
        self.name = name
            
   def displayCount(self):
        print(self.empCount)

赋值

e = Employee("小红")
# 调用属性, 方法
e.empCount = 10
e.displayCount()

继承

class Child(Employee): # 定义子类
  name = "zi"

  def __init__(self):
    print("call Child __init__()")

  # 方法重写
  def displayCount(self):
    print(self.name)

c = Child()          # 子类实例
c.displayCount()         # 子类调用重写方法
