如何在Python中从列表创建嵌套字典? [英] How to create a nested dictionary from a list in Python?

问题描述

我有一个字符串列表: tree_list = ['Parents'，'Children'，'GrandChildren']

I have a list of strings: tree_list = ['Parents', 'Children', 'GrandChildren']

如何获取该列表并将其转换为这样的嵌套字典?

How can i take that list and convert it to a nested dictionary like this?

tree_dict = {
    'Parents': {
        'Children': {
            'GrandChildren' : {}
        }
    }
}

print tree_dict['Parents']['Children']['GrandChildren']

推荐答案

最简单的方法是从内而外地构建字典:

This easiest way is to build the dictionary starting from the inside out:

tree_dict = {}
for key in reversed(tree_list):
    tree_dict = {key: tree_dict}
