问题描述
我想知道是否有一种方法可以在python中用键初始化字典,但没有相应的值,直到我设置它们.如:
I was wondering if there was a way to initialize a dictionary in python with keys but no corresponding values until I set them. Such as:
Definition = {'apple': , 'ball': }
然后我可以设置它们:
Definition[key] = something
我只想初始化键,但是直到以后必须设置它们时,我才知道相应的值.基本上,我知道要添加找到值的键.谢谢.
I only want to initialize keys but I don't know the corresponding values until I have to set them later. Basically I know what keys I want to add the values as they are found. Thanks.
