Python Chain getattr作为字符串 [英] Python Chain getattr as a string

问题描述

import amara
def chain_attribute_call(obj, attlist):
    """
    Allows to execute chain attribute calls
    """
    splitted_attrs = attlist.split(".")
    current_dom = obj
    for attr in splitted_attrs:
        current_dom = getattr(current_dom, attr)
    return current_dom

doc = amara.parse("sample.xml")
print chain_attribute_call(doc, "X.Y.Z")

为了将对象作为字符串执行链属性调用，我必须开发上面的笨拙代码段.我很好奇是否会有一个更聪明/更有效的解决方案.

In oder to execute chain attribute calls for an object as a string, I had to develop the clumsy snippet above. I am curious if there would be a more clever / efficient solution to this.
