问题描述

我正在努力解决以下问题:我想像这样转换 OrderedDict:

I am struggling with the following problem: I want to convert an OrderedDict like this:

OrderedDict([('method', 'constant'), ('data', '1.225')])

到这样的常规字典中:

{'method': 'constant', 'data':1.225}

因为我必须将它作为字符串存储在数据库中.转换后，顺序不再重要，所以我无论如何都可以保留有序功能.

because I have to store it as string in a database. After the conversion the order is not important anymore, so I can spare the ordered feature anyway.

感谢任何提示或解决方案，

Thanks for any hint or solutions,

推荐答案

>>> from collections import OrderedDict
>>> OrderedDict([('method', 'constant'), ('data', '1.225')])
OrderedDict([('method', 'constant'), ('data', '1.225')])
>>> dict(OrderedDict([('method', 'constant'), ('data', '1.225')]))
{'data': '1.225', 'method': 'constant'}
>>>

但是，要将其存储在数据库中，最好将其转换为 JSON 或 Pickle 等格式.使用 Pickle，您甚至可以保持订单！

However, to store it in a database it'd be much better to convert it to a format such as JSON or Pickle. With Pickle you even preserve the order!
