How to use Python to copy an article and then paste the article completely, and paste the image/text (format)/link of the article together?

My system is OS X, using Python

I use COMMAND + C to copy an article on a website (including images/links/text in the article).

then

I am using COMMAND+V to paste the article just copied, on the page of the published article on another website.

The result: the image and the text and the links (including the style) are all pasted.

However, I can't do this with the Python Pyperclip module.

Excuse me, how do I use Python to copy and paste articles (including images\links\text in the article)?

Thank you!
