But you're only importing, right? I mean, you aren't returning anything nor receiving the arguments... Can you explain bit more, please?

fact

I think my code is actually faster, but can someone confirm?

contains is the function for "in" operator. When we import it as "include", that does the trick.

how does this even work?

Quite a tedious job!

Good!

i am sorry if i heart anyone's feelings. that person really did a hard job, maybe because he don't know some packages. but that's why practice makes perfect.

Instead of criticising someone's work, how about suggesting alternatives?

f-strings are the best

Even simpler than lambda and/or without relying on other modules

ahh so easy to overlook. clever!
