对象可以包含任意数量和类型的数据。Python的动态特性(dynamic nature)允许在运行时为对象添加新的属性和方法。 类和模块的动态性: 类和模块都是在运行时创建的,我们可以在程序运行过程中定义新的类和模块。 创建后,类和模块也可以被修改。例如,可以在运行时为类添加新的方法或属性,或者修改现有的方法。 在下面示例中,
print self.msg print '===dynamic create class==='+ '*'*50 MyClass = type('MyClass',(object,),{"a":123,"b":"summer","msg":"test message","echo_msg":echo_msg}) print MyClass.a myclass = MyClass() myclass.echo_msg() print myclass.a,myclass.b print '===dynamic create ...

Table 4-1 isn’t really complete, because everything we process in Python programs is a kind of object. For instance, when we perform text pattern matching in Python, we create pattern objects, and when we perform network scripting, we use socket objects. These other kinds of objects are ...

Common Mistake #10: Misusing the__del__method Let’s say you had this in a file calledmod.py: import fooclassBar(object): ...def__del__(self): foo.cleanup(self.myhandle) And you then tried to do this fromanother_mod.py:
