I was trying to create and deploy a smart contract using pyTEAL following the official guide, but something went wrong…

Welcome to Algorand!

Can you provide the exact commands you typed as well as the content of all the relevant files (including `peridic_payment_deploy.py`?)

Write code and bash commands between triple backquotes ``` for better formatting.

Perhaps this is it?
