Rr531/YouTube-SubBot ? reverse-engineered prompt

Build me a simple Python tool related to YouTube subscriber tracking.

I want something easy to run that can check a channel’s subscriber count, keep a log of changes over time, and show the results in a clear way in the terminal or a small interface. If it needs current setup details from online docs, feel free to look them up.

Please make it beginner friendly, with straightforward instructions to run it, and include any setup steps for credentials or API access if needed. I’d like the code to be organized cleanly, with the main logic separated from any helper functions, so it’s easy to understand and improve later.

If there are two parts to the project, please make both work together as one complete project.
