I'm following along with the brownie documentation, and have come across this:

classbrownie.network.contract.Contract(address_or_alias, owner=None) A deployed contract that is not part of a Brownie project.

address_or_alias: Address of the contract. owner: An optional Account instance. If given, transactions to the contract are > sent broadcasted from this account by default.

>>> from brownie import Contract
>>> Contract("0x79447c97b6543F6eFBC91613C655977806CB18b0")
<Token Contract object '0x79447c97b6543F6eFBC91613C655977806CB18b0'>

However, if I take the same code and put it into a script called call.py I get an error:

brownie run scripts/call.py --network mainnet

Brownie v1.16.4 - Python development framework for Ethereum

MultiCallProject is the active project.

You need to have it in your main function.

Change

contract = Contract("0x79447c97b6543F6eFBC91613C655977806CB18b0")

to

def main():
    contract = Contract("0x0000000022D53366457F9d5E68Ec105046FC4383")
    print("ko")

And it'll pull the contract in.
