I have tried to explore https://github.com/polkascan/py-substrate-interface, but didn't find any example, so I am wondering if I want to send asset like USDT from statemine parachain to another parachain?

You don't need a bridge at all, Polkadot includes a message transport protocol for its parachains. I'd check out Subscan's XCM explorer to look at examples of asset transfers and how those transactions are constructed. For example, here is a transfer of some USDT from Statemine to Moonriver.


Like Joe is saying, you need to open HRMP channels and then send an XCM. You can see the actual XCM Joe referenced here:
