如何用3个列表在Python中创建嵌套字典 [英] How to Create Nested Dictionary in Python with 3 lists

问题描述

让我们假设，我已经创建了3个列表，并且我想为其创建字典.例如

Let us Suppose, I have created 3 lists and I want to create a dictionary for it. e.g.

a= ['A', 'B', 'C', 'D']
b =[1, 2, 3, 4]
c = [9, 8, 7, 6]

现在，我要创建一个像这样的字典:

Now What I want is to create a dictionary like this:

{'A':{'1' :'9'} , 'B':{'2':'8'}, 'C':{'3':'7'} , 'D':{'4':'6'}}

有可能，有人可以帮我吗?

is it possible, Can Someone Help me on this?

推荐答案

您可以从zip -ed列表中创建字典，并将int值转换为字符串-如果我理解您的问题正确的话

You can create the dictionary from zip-ed lists and convert the int values to strings - if I understood your question proper

dct = {x: {str(y): str(z)} for x, y, z in zip(a,b,c)}

输出:

{'A': {'1': '9'}, 'C': {'3': '7'}, 'B': {'2': '8'}, 'D': {'4': '6'}}
