Opensea Smart Contract Interaction

Hello, I want to make an NFT purchase by interacting with Opensea Smart Contract ( probably atomicMatch function related )

You can deliver this to me by making a Smart Contract or by making it on a python web3 library.

My purpose in creating this order is to learn about this topic
