Ethereum – How to Create a New Account Using web3.py

pythonweb3.py

Using web3.py, I'm gonna create new account, however, I can't get passphrase.

Generates a new account in the node’s keychain encrypted with the
given passphrase. Returns the address of the created account.

web3.personal.newAccount('the-passphrase')
['0xd3cda913deb6f67967b99d67acdfa1712c293601']

I saw this paragraph in Web3.py docs.
How to generate passphrase?

'the-passphrase' is password to be supplied by you, which will be used to encrypt new account's private key.

So when you will access this new account, system will ask for password which was used to encrypt account's private key.

The RPC methods under personal_* are not exposed by default. The question set it up correctly. (although today, the correct arg is --jsonrpc-apis 'eth,web3,personal').

If you are still failing to connect, and you are using IPC, note that the argument above only sets up calls over HTTP. If you are using IPC, you need to use --ipc-apis 'eth,web3,personal' instead.

If you would rather not expose the personal APIs, for security reasons, you can use the eth_accounts RPC call.

>>> web3.eth.accounts
['0x...']

Two things: Be sure that the checksum of the addresses is correct. you can do:

web3.toChecksumAddress('0xbcd8ffbb0f8a5410194ab5a3badf46caaa693098') // for the contract address

Also, try defining the from in transact, like this:

contract_bid.functions.addBid(10,"xyzz",1234,5600).transact({'from': 'your_account'})

Hope this helps.
