Lesson 4: Error message using chain_id in buildTransaction()

[selinimsibiri]

Hello
this is my code:

_from solcx import compile_standard, install_solc
import json
from web3 import Web3

with open("./SimpleStorage.sol", "r") as file:
    simple_storage_file = file.read()

print("Installing...")
install_solc("0.6.0")

# Solidity source code
compiled_sol = compile_standard(
    {
        "language": "Solidity",
        "sources": {"SimpleStorage.sol": {"content": simple_storage_file}},
        "settings": {
            "outputSelection": {
                "*": {
                    "*": ["abi", "metadata", "evm.bytecode", "evm.bytecode.sourceMap"]
                }
            }
        },
    },
    solc_version="0.6.0",
)
with open("compile_code.json", "w") as file:
    json.dump(compiled_sol, file)


# get bytecode
bytecode = compiled_sol["contracts"]["SimpleStorage.sol"]["SimpleStorage"]["evm"][
    "bytecode"
]["object"]

# get abi
abi = compiled_sol["contracts"]["SimpleStorage.sol"]["SimpleStorage"]["abi"]

# for conneting to ganache
w3 = Web3(Web3.HTTPProvider("http://127.0.0.1:7545"))
chain_id = 1337
my_address = "0x66487dD584Ed8bB02064f2d855659882a5772134"
private_key = "0xe02ab2b4fddde5ba4ec22fc971359983e2687b21cf30544d85ab2991080aec13"

# create the contract in python
SimpleStorage = w3.eth.contract(abi=abi, bytecode=bytecode)
# print(SimpleStorage)

# get the latest transactions
nonce = w3.eth.getTransactionCount(my_address)
print(nonce)

# 1.build a transaction
# 2.Sign a transaction
# 3.Send a transaction
transaction = SimpleStorage.constructor().buildTransaction(
    {"chainId": chain_id, "from": my_address, "nonce": nonce}
)
# print(transaction)_

and here is the thing i have no idea what it is:

Nice, some users also has problems with cytools, but thanks, this could be handy for other users.

how would I download that specific version? Is this still recommended as a fix even though my version is now 5.30.0?
