Best languages for:

I am wondering what is the best language to use (preferably on codecademy) when making something that will enter information in an online forms and wait for a response, such as buying something.

I don’t mind how hard it is to learn as I’m wiling to put in the time however I would like there to be a comprehensive tutorial somewhere online.

I was also wondering what the best language to learn would be if I were to be hoping to scrape all images with a certain tag on a website… let’s say rule34 as an example, it needs to first enlarge the images and then save them to a specific location on my computer.

Lastly would anyone know of a good language to learn when needing to create a discord bot that prints things (such as web browser activity) to a chat in a server.

Thanks in advance.
