本文通过一个简单的Python代码示例展示了如何区分类的属性和项。定义了一个名为MyClass的类，并通过__getitem__方法实现了对类实例的字典式访问。通过setattr设置了类实例的属性，展示了属性和项的不同调用方式。

This recipe is a small code snippet of showing how to distinguish attribute and item in Python language.


class MyClass(object):

	def __getitem__(self, name):
		return "this is from get item function"
	pass
	
def action():
	return "play basketball this afternoon"	
	
	
if __name__ == "__main__":

	me = MyClass()
	setattr(me,"weather","it is sunshine")
	setattr(me,"event",action)

	print me.weather
	print me['event']
	print me.event()
