Assuming you are going to discard the original dicts in favor of the merged one (which is typically the case in most situations), there is no need to "copy and update". You can simply run the update() method on one of the dicts and consider it the final which will be faster and efficient:

Yeah, that works too! Though, I’m not a huge fan of introducing an alias just for the sake of performance, but that’s just me.
Also, if we’re talking hypotheticals, it might be useful to maintain the old dictionaries since an update is going to overwrite any duplicate keys.
