Correct, you want to exclude the .venv directory. But what about the things you are installing into the .venv. Is there enough comitted here for me to be able to re-create your venv on my machine? which file is missing?

Part of the task spec is finding a way to write this without you having to declare this array yourself. can you figure out how to get the animals directly from the library?

"beavis", "cheese", "cow", "daemon", "dragon", "fox",
"ghostbusters", "kitty", "meow", "miki", "milk", "octopus",
"pig", "stegosaurus", "stimpy", "trex", "turkey", "turtle", "tux"
]

if animal not in supported_animals:
print(f"usage: cowsay [-h] [--animal {{{','.join(supported_animals)}}}] message [message ...]")
print(f"cowsay: error: argument --animal: invalid choice: '{animal}' (choose from {','.join(supported_animals)})")
sys.exit(1)

output = cowsay.get_output_string(animal, text)
print(output)
