I want to use Python 3 to manage the metamak plugin on the browser, such as adding users with interfaces

For example, rpc?

Hi could you share more details about rpc case what are you trying to do. Are you familiar with Use MetaMask SDK | MetaMask developer documentation

The main objective is to interact with MetaMask through web3 and JavaScript.

MetaMask via RPC or web3

Use web3.py`to make RPC calls to interact with Ethereum blockchain.

examole:

from web3 import Web3

Connect to a local Ethereum node

web3 = Web3(Web3.HTTPProvider(‘// localhost : 8545’))

Check if connection is successful

if web3.isConnected():
print(“Connected to Ethereum network”)
else:
print(“Connection failed”)

Example: Getting the balance of an address

address = ‘0xYourAddressHere’
balance = web3.eth.get_balance(address)
print(f’Balance: {web3.fromWei(balance, “ether”)} ETH’)

Example: Sending a transaction

tx = {
‘from’: ‘0xYourAddressHere’,
‘to’: ‘0xRecipientAddressHere’,
‘value’: web3.toWei(0.01, ‘ether’),
‘gas’: 21000,
‘gasPrice’: web3.toWei(‘50’, ‘gwei’)
}

private_key = ‘YourPrivateKeyHere’
signed_tx = web3.eth.account.sign_transaction(tx, private_key)
tx_hash = web3.eth.send_raw_transaction(signed_tx.rawTransaction)
print(f’Transaction hash: {tx_hash.hex()}')
