How to differentiate between BTC transactions and BRC20 transactions on a blockchain?

How to differentiate between BTC transactions and BRC20 transactions on a blockchain using the RCP interface?

This is a transaction record that contains BRC20 tokens which I found on a blockchain explorer.

When I using the RPC to scan blocks and retrieve transaction records like this one, how can I use Python3 to determine whether the transaction is a BRC20 or BTC transaction?

How to analyze ? Witness component 1 , Witness component 2, Witness component 3.

If I want a complete analysis, what should I do.

The analogy is as follows:
