For this example, we will write a Metaclass that raises aValueErrorwhen a negative value is received inattributes. classPositiveNumbersMeta:def__new__(cls,class_name,bases,attributes):forattr,valueinattributes.items():ifisinstance(value,(int,float))andvalue<0:raiseValueError(f"Negative values are...
我们再看一个例子。 class Crazy(object): def __init__(self): print("I") def __del__(self): print("D") Output: >>> Crazy() is Crazy() I I D D False >>> id(Crazy()) == id(Crazy()) I D I D True 现在你可以发现, 不同的调用方法会对实例销毁的时间产生不同的影响。
