在Python中，我有字典.如何更改此词典的键? [英] In Python, I have a dictionary. How do I change the keys of this dictionary?

问题描述

假设我有一本非常复杂的字典.

Let's say I have a pretty complex dictionary.

{'fruit':'orange','colors':{'dark':4,'light':5}}

无论如何，我的目标是扫描此复杂的多级词典中的每个键.然后，将"abc"附加到每个键的末尾.

Anyway, my objective is to scan every key in this complex multi-level dictionary. Then, append "abc" to the end of each key.

因此它将是:

{'fruitabc':'orange','colorsabc':{'darkabc':4,'lightabc':5}}

你会怎么做?

推荐答案

键不能更改.您将需要添加一个具有修改后值的新键，然后删除旧键，或者使用dict理解或类似方法创建一个新dict.

Keys cannot be changed. You will need to add a new key with the modified value then remove the old one, or create a new dict with a dict comprehension or the like.
