• Then go to contract.py on line 9 you see w3 so change the url there
• after that change the account address ,key(private_key) and contract address in contract.py
• key = '<account-private-key>'
• account = w3.toChecksumAddress('<your-account-address>')
• address = w3.toChecksumAddress('<contract-address>')
