将字典加在一起，Python [英] Adding dictionaries together, Python

问题描述

我有两本词典，我希望能够将它们制作成一本:

I have two dictionaries and I'd like to be able to make them one:

像这样的伪 Python 会很好:

Something like this pseudo-Python would be nice:

dic0 = {'dic0': 0}
dic1 = {'dic1': 1}

ndic = dic0 + dic1
# ndic would equal {'dic0': 0, 'dic1': 1}

推荐答案

如果您有兴趣在不使用中间存储的情况下创建新的 dict :(这比使用 dict 更快，而且在我看来更干净.items())

If you're interested in creating a new dict without using intermediary storage: (this is faster, and in my opinion, cleaner than using dict.items())

dic2 = dict(dic0, **dic1)

或者，如果您愿意使用现有的字典之一:

Or if you're happy to use one of the existing dicts:

dic0.update(dic1)
