#-*-coding:utf-8 class Person: __privateName=None; count=0;#既可以被实例对象引用,也可以被当做静态对象引用,NND,好混乱。 def __init__(self,name): self.count+=1 Person.count+=2 print(‘%s has been created‘ % name) self.__privateName=name; self.name=name def printPrivateName(self): print(‘Private Name: %s‘ % self.__privateName) def printName(self): print(‘Name is %s‘ % self.name) if __name__==‘__main__‘: zili=Person(‘zili‘) Person.__privateName=‘zhangsan‘ print(Person.__privateName) zili.__privateName=‘zhangsan‘ print(‘jiangyao shuchu :%s‘ % zili.__privateName) zili.printName() zili.printPrivateName() print(zili.count) print(Person.count) Person.ABC=‘abcvalue‘ print(Person.ABC) else: print("I‘m importing by some other guys.")
独立运行这个文件的时候__name__是‘__main__‘,在被别的Python import的时候,就会执行else块,在继承体系中恰当运用可以非常好的协同工作。
说到协同工作这几个字,真感觉这个设计是Python的天才式设计。
