Welcome to the forum.
Unfortunately there are few issues with your request…
This forum is here to assist with your own learning of how to use Blynk, it’s commands, and it’s features… not teach anyone how to program. Nor do we code all, or even part of it for you.
And by help learn, we mean you first read through all the readily available Documentation and examples (all those links are at the upper right of this page… scroll up if you don’t see them), and learn how they work… but you can certainly ask questions as you go… and we assist with those questions as best able.
The other issue would be that the python variation of Blynk is in Alpha stage… in fact even the javascript method is a little lean on documentation… so even assisting on basic Blynk related questions for those languages will be limited to a very few individuals.
I recommend you start off with a little reading and take it from there…
