val = dict.__getitem__(self, key)
KeyError: 'address'
怎么解决这个问题
字典里没有这个key
具体要看你的代码呀
整个代码文件有点长，这一部分可以解决问题吗，谢谢！
class Section(dict):
"""
A dictionary-like object that represents a section in a config file.
It does string interpolation if the 'interpolation' attribute
of the 'main' object is set to True.
Interpolation is tried first from this object, then from the 'DEFAULT'
section of this object, next from the parent and its 'DEFAULT' section,
and so on until the main object is reached.
A Section will behave like an ordered dictionary - following the
order of the ``scalars`` and ``sections`` attributes.
You can use this to change the order of members.
Iteration follows the order: scalars, then sections.
