## Formatting: Vyper & Python We're going to go into fuzz testing in just a minute, but first we'll take a look at some ways to format our Vyper and Python code. Our code looks like this: ```python script from moccasin.boa.tools import VyperContract from eth_utils import to_wei INITIAL_SUPPLY = to_wei(1000, "ether") from contracts import snek_token def deploy() -> VyperContract: snek_contract = snek_token.deploy(INITIAL_SUPPLY) print(f"Deployed to {snek_contract.address}") return snek_contract def moccasin_main() -> VyperContract: return deploy() ``` This code is not formatted well, with imports in a strange order. We can either manually change this code, or we can use a tool. Let's go ahead and install the **ruff** formatter. We can do this through UV's command palette by typing "format document" and hitting enter. We can also format our code in the terminal using the following command: ```bash uv run ruff check --select I--fix ``` This will automatically fix a lot of our imports. What about Vyper? We can also format our Vyper code using a tool called **mamushi**. This tool can be installed using the following command: ```bash uv add mamushi ``` After installing mamushi, we can run the following command to format our contracts folder: ```bash uv run mamushi contracts/ ``` This will reformat our entire `snek_token.vy` file to be much nicer looking.
