python通过点操作符和reduce遍历对象的属性的代码
如下的资料是关于python通过点操作符和reduce遍历对象的属性的内容,应该能对码农们有较大用途。
class Klass(object):
def __getattr__(self, name):
"""
Locate the function with the dotted
attribute.
"""
def traverse(parent, child):
if instance(parent, str):
parent = getattr(self, parent)
return getattr(parent, child)
return reduce(traverse, name.split('.'))
