eth_abi deprecation warning for abi.encode_abi

[Polsaker]

• Version: 6.0.0b4
• Python: 3.10
• OS: osx

What was wrong?

Contract calls raise a DeprecationWarning due to encode_abi being renamed to encode in eth_abi:

    return self.contract.functions.decimals().call()

E       DeprecationWarning: abi.encode_abi() and abi.encode_abi_packed() are deprecated and will be removed in version 4.0.0 in favor of abi.encode() and abi.encode_packed(), respectively

How can it be fixed?

Call encode instead of encode_abi as directed by the eth_abi warning.

Thanks for the heads up!

There are a bunch of decode_abi calls left in https://github.com/ethereum/web3.py/blob/master/web3/contract.py
