Most proxy contracts typically have a public variable defined as a:
address public implementation;
Which defines the address of the implementation contract. You could then call it as a view function in python, with something like:
proxy_contract = web3.eth.contract(address=address, abi=abi_string)
implementation_contract_address = proxy_contract.functions....
in order to be on top of the big transaction, the front-runner would use more gas allocation than that big transaction. if you add even 1 wei over a trx you would be able to jump on top of it in the block index count.
so that's how it is done.
Just for info, there are multiple ways being implemented to circumvent front running transactions like personalized ...
