本文介绍了Python Chain getattr作为字符串的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
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.
推荐答案
只需从:
from functools import reduce
reduce(getattr, "X.Y.Z".split('.'), doc)
