I am trying to deploy smartcontract on python. Everything goes nice except when I call the getter function of smart contract, it throws an error. It replaced the main.py in py-eth already and it solved all initial errors.

@MunimShabir I'm not able to reproduce the error you're seeing. I do notice some syntax errors, however. You declare the w3 variable twice (which shouldn't matter in this context, just an observation), and I don't think that evm_version is a valid key in the compile_standard JSON. Feel free to update the code snippet and I can help with troubleshooting if you still need it.

@kclowes This is how you can reproduce the issue. I am not sure this is an issue with web3 v5 or eth-tester.

ethereum/eth-tester#167

[arjunaskykok]

I found the thing that caused this issue. The execute_transaction is removed in a commit in py-evm project: ethereum/py-evm@1992368#diff-2d5d99f4dd8df9b29c7486b27678f9fb

The replacement is apply_transaction method. Fixing this issue is easy. Creating test is a little bit confusing.

By the way, the issue is in eth_tester project, not web3.py project. So I think this issue can be closed.

Thanks for digging into this @arjunaskykok! Closing in favor of ethereum/eth-tester#167
