内置方法 说明 __init__(self,...) 初始化对象,在创建新对象时调用 __del__(self) 释放对象,在对象被删除之前调用 __new__(cls,*args,**kwd) 实例的生成操作 __str__(self) 在使用print语句时被调用 __getitem__(self,key) 获取序列的索引key对应的值,等价于seq __len__(self) 在调用内联函数len()时被调用 __cmp__(stc,dst) 比较两个对象src和dst __getattr__(s,name) 获取属性的值 __setattr__(s,name,value) 设置属性的值 __delattr__(s,name) 删除name属性 __getattribute__() __getattribute__()功能与__getattr__()类似 __gt__(self,other) 判断self对象是否大于other对象 __lt__(slef,other) 判断self对象是否小于other对象 __ge__(slef,other) 判断self对象是否大于或者等于other对象 __le__(slef,other) 判断self对象是否小于或者等于other对象 __eq__(slef,other) 判断self对象是否等于other对象 __call__(self,*args) 把实例对象作为函数调用
