add .gitignore

[knorth55]

I add .gitignore in this repo.
.pyc files are generated when you run python.

In case this does not get picked up. I have .pyc in my global gitignore file. I don't see a use-case where I would ever want this under version control 🙂

what do you mean?
you want to say we dont need this pr?
it depends on global gitignore file, and some case we dont have proper gitignore global file, like docker image.
so i made this pr.

I'm not saying this should not be merged (I'm not a maintainer here).
I merely thought I'd give you a pointer on how this can be solved in case this never gets merged.

I see.
Thank you for your kind information!
