@great-library-25724 I don't think you need to be an expert, most of the code you'll be writing will be quite basic.

Thanks, I can understand basics in python , like varibale , array, loop , conditional statements .. but classes /objects and complex functions are out of my mind .. as i use daily ansible /terraform / bash and now days kubernetes so bit of helm… i learned python before 2 years but honestly it did not useful to my job as ansible / terraform has own kind of language na set of rules and grammers

I wouldn't be concerned at all, there are plenty of examples on the Pulumi docs and all you need most of the times is just basic understanding of object oriented programming.

it looks like developer tool as there is not a single binary like terraform does and then take care things..
