Even if we remove an attribute from the above code, we can still add it afterward usingsetattr(). Different Syntaxes for Set Attribute in Python Thesetattr(object,name,value)is the shorter syntax used instead of using theobject.__setattr__(name, value), making both methods the same. ...
If you attempt to change anamedtupleobject’s attribute value, you try to modify an immutable object. Consequently, Python raises theAttributeError: can't set attribute. Fix #1: Use the namedtuple._replace() Method The easiest way to fix theAttributeError:can't set attributeis to create a n...

若descr为空(未找到),则最终抛出 AttributeError 异常,结束查找。 由描述符类产生的实例进行属性的调用/赋值/删除,并不会触发这三个方法 描述符的对象 x 其实是类People的类属性,那么可不可以把它变成实例属性呢 classDesc():def__init__(self,key): ...

把错误消息改成"'LineItem' classhas no such attribute" 更好。最好能给出缺少的属性名,但是在 这个示例中,描述符不知道托管属性的名称,因此目前只能做到这样。此外,为了给用户提供内省和其他元编程技术支持,通过类访问托管属 性时,最好让 __get__ 方法返回描述符实例。示例 20-3 对示例 20-2 做了小幅...
