Hello! Tell me, is it possible to track events in solidity from another contract and send transactions automatically when an event is called?
Is there such a mechanism or something similar? So that it automatically generates a transaction without the knowledge of the user

to generate a valid transaction, you need to sign the raw transaction with a pkey
so nope
contracts cannot do that (thank vitalik)

But it's possible to do so with a python script right?
Also, what about to query the state of a contract when an event occurs?

you can subscribe to events and do actions once you receive an update

What about in a contract, if I want to read the state of a contract after an event occured in another contract?
Can I do that!

of course you can, still from a script.
A contract doesn't know past or future state, nor understand there is another block or network at all

view evm as a virtualbox without internet, when the execution it's complete it shutdown
so you cannot query events, past states (without saving them on storage)
