How can I get the deployed contract's address from a ContractContainer object in Brownie?

Question

I want to chain contract deployment, where the second contract gets as a parameter the address of the first using Brownie:

from brownie import ContractA, ContractB , accounts

def main():
    acct = accounts[0]
    ContractA.deploy({'from': acct})
    ContractB.deploy(ContractA.address, {'from': acct})

With web3 and Truffle, the deployed contract instance can be imported and we get its address with .address. However, brownie CountractContainer are function objects and I can't understand how to get the deployed address.

Here is your code with some changes that should work.

from brownie import ContractA, ContractB , accounts

def main():
    acct = accounts[0]
    container = ContractA.deploy({'from': acct})
    ContractB.deploy(container.address, {'from': acct})
