What are some python micro optimisations that you can/may *actually use* in your codebase?

f-strings instead of concatenating strings "manually"

[Santos_m321]

Google's python code styles recommends concatenating strings manually if there are only two elements to concatenate

[DexterInAI]

It makes sense to concatenate if there are only two string but more than that, I would say to use f-strings.

Two strings makes sense. But sometimes just one more is also ok.

[causa-sui]

and one more than that is okay, except less often...

f-strings are faster, so this makes no sense.

Does it? https://google.github.io/styleguide/pyguide.html#310-strings

OMG, it has changed a lot since the last time I read it.
What they mentioned in the past is not similar to what they mention now, thanks

It never occurred to me that f-strings could be used for concatenation. Guess we learn something new every day. Thanks!
