我有一个班级(下):
class InstrumentChange(object):
'''This class acts as the DTO object to send instrument change information from the
client to the server. See InstrumentChangeTransport below
'''
def __init__(self, **kwargs):
self.kwargs = kwargs
self._changed = None
def _method_name(self, text):
return text.replace(' ','_').lower()
def _what_changed(self):
''' Denotes the column that changed on the instrument returning the column_name of what changed.'''
if not self._changed:
self._changed = self._method_name(self.kwargs.pop('What Changed'))
return self._changed
def __getattr__(self, attr):
for key in self.kwargs.iterkeys():
if self._method_name(key) == attr:
return self.kwargs[key]
def …这是我需要挑选的课程:
class sdict(dict):
def __getattr__(self, attr):
return self.get(attr, None)
__setattr__= dict.__setitem__
__delattr__= dict.__delitem__
__reduce__ = dict.__reduce__
在我看来__reduce__应该照顾酸洗,但相反:
