我在代码中使用了以下内容:
class Structure(dict,object):
""" A 'fancy' dictionary that provides 'MatLab' structure-like
referencing.
"""
def __getattr__(self, attr):
# Fake a __getstate__ method that returns None
if attr == "__getstate__":
return lambda: None
return self[attr]
def __setattr__(self, attr, value):
self[attr] = value
def set_with_dict(self, D):
""" set attributes with a dict """
for k in D.keys():
self.__setattr__(k, D[k])
总而言之,它适用于我的目的,但我注意到,只有方法选项卡完成才能用于继承自Structure的另一个自定义类中的方法,而不是属性。我也做了这个测试,我发现结果有点奇怪:
In [2]: d = Structure()
In [3]: d.this = 'that'
In [4]: d.this
Out[4]: 'that'
In [5]: d.th<tab>
NOTHING HAPPENS
In [6]: class T():
...: pass
...:
In [7]: t = T()
In [8]: t.this = 'cheese'
In [9]: t.th<tab>
COMPLETES TO t.this
Out[9]: 'cheese'
我需要将哪些内容添加到我的类中才能使标签完成工作以获取属性?
答案 0 :(得分:16)
添加此方法:
def __dir__(self):
return self.keys()
