如何将嵌套字典转换为具有关键命令的列表 [英] How to convert nested dictionary to list with key orders

问题描述

我想从嵌套字典中列出一个列表:

I want to make a list out of the nested dictionary:

 {'Name': {'20': 'Paul Merrill', '21': 'Brynne S. Barr', }, 
 'Phone': {'20': '1-313-739-3854', '21': '939-4818', }, 
 'Address': {'20': '916-8087 Vehicula Rd.', '21': '878-2231 Suspendisse Rd.', },
 'City': {'20': 'Le Mans', '21': 'Wilhelmshaven',}

以'20'作为标识符的列表，因此将如下所示:

to a list with '20' as the identifier, so it will be something like this:

['20', 'Paul Merril', '1-313-739-3854', '916-8087 Vehicula Rd.', 'Le Mans']

我尝试使用值和键选项，但它们似乎不起作用. 有人可以帮我吗?

I have tried to use value and key options, but they don't seem to work. Could someone help me with this?

推荐答案

使用或者@Henry Yik的解决方案，谢谢:

Or solution from @Henry Yik, thank you:

L = [v.get("20") for v in d.values()]
print (L)
['Paul Merrill', '1-313-739-3854', '916-8087 Vehicula Rd.', 'Le Mans']

如果还需要添加20:

L = ['20'] + L

或者:

L = ['20', *L]

print (L)
['20', 'Paul Merrill', '1-313-739-3854', '916-8087 Vehicula Rd.', 'Le Mans']
