This kind of micro optimizations don't make much sense in Python. They complicate the code, and you are still 100 times slower than compiled languages.
It really… doesn’t have to complicate. And I disagree that optimising python code is never necessary. Not everybody is writing 100-line one-off glue scripts.
Also, you are somewhat changing the topic from “what is an example of when you might want to is-compare two dicts”, no?
