class A: def __init__(self,a): self.a=a def __add__(self,others): print('this is a magic method') return [self.a,others.a] >>>a=A(1) >>>b=A(3) >>>c=a+b#自定义的__add__方法,实现是将两个对象的a属性合并到一个列表中 this is a magic method#+调用的是__add__方法...
>>>a1 = A("hello") >>>a2 = A("world") >>>print (a1 + a2) >>>overwrite add method >>>"hello---world" 我们重写了__add__方法,当Python识别"+"操作时,会自动调用重写后的__add__方法。可以看到,魔法方法在类或对象的某些事件出发后会自动执行,如果希望根据自己的程序定制特殊功能的类,那么...
