Retrieving Contract instance from .abi and address

Question

Having the .abi file and the address of a Smart Contract. Can I somehow retrieve the smart contract object instance?

I know for the web3.js we could do something like:

var inst = eth.contract(abi).at(address))

But this doesn't work for the web3py. I am new to this syntax. How can I solve this?

Answer 1

You can do:

contract = web3.eth.contract(abi=abi,address=address)

See the official documentation here.

Answer 2

Calling web3.eth.contract in web3.py uses the following syntax:

from web3 import Web3

w3 = Web3()

# modify these values
abi = {}
address = "0x00..."

contract = w3.eth.contract(address=address, abi=abi)

The returned value is a Contract object.
