here is the code I'm trying to run (from Patric's course), please consider that this is my first time into coding and it has been two weeks trying to solve this issue !
from solcx import compile_standard from web3 import Web3 import json
with open("./SimpleStorage.sol", "r") as file: simple_storage_file = file.read()
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("compiled_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"]
connecting to ganach w3 = Web3(Web3.HTTPProvider("http://127.0.0.1:7545")) chaind_id = 5777
my_address = "0xa1d2a440E4E75bcA442107162DE8C276D637a0eF" 'private_key = os.getenv("0x170ab1d384e1d218ccd8ec332dfa334f8e9980f008043ff04e99a8154322bf06")
cteating the contract in python SimpleStorage = w3.eth.contract(abi=abi, bytecode=bytecode) print(SimpleStorage)
I tried all the solution I found; installed cyphon, installed legacy but nothing changed. and this is was I see on the terminator:
