## Deploying to pyevm With TitanoBoa We've created a virtual environment and installed TitanoBoa. Now we can start to use TitanoBoa to work with our Vyper contracts! We'll start with creating a new Python file called `deploy_favorites_pyevm.py`. We can then start to write some code in the file. ```python if __name__ == "__main__": main() ``` We'll also define a main function. We'll start out with a simple print statement for now. ```python def main(): print("Let's read in the Vyper code and deploy it!") ``` Our next step is to actually load our contract from the `favorites.vy` file. We can do this by importing the `boa` library and using the `boa.load()` function. ```python def main(): print("Let's read in the Vyper code and deploy it!") favorites_contract = boa.load("favorites.vy") ``` We can see what type of object our `favorites_contract` is using the `type()` function. ```python def main(): print("Let's read in the Vyper code and deploy it!") favorites_contract = boa.load("favorites.vy") print(type(favorites_contract)) ``` We can see from our output that our `favorites_contract` is of the type `boa.contracts.vyper.vyper_contract.VyperContract`. ```bash python deploy_favorites_pyevm.py ``` Let's read in the Vyper code and deploy it! <class 'boa.contracts.vyper.vyper_contract.VyperContract'> We can use type hints to help us understand what kind of objects our variables are. For example, we can type hint our `favorites_contract` variable to be a `VyperContract`. ```python def main(): print("Let's read in the Vyper code and deploy it!") favorites_contract: VyperContract = boa.load("favorites.vy") print(type(favorites_contract)) ``` To use the `VyperContract` type hint, we'll need to import it from the `boa.contracts.vyper.vyper_contract` module. ```python from boa.contracts.vyper.vyper_contract import VyperContract def main(): print("Let's read in the Vyper code and deploy it!") favorites_contract: VyperContract = boa.load("favorites.vy") print(type(favorites_contract)) ``` We can then run this code again. ```bash python deploy_favorites_pyevm.py ``` Let's read in the Vyper code and deploy it! <class 'boa.contracts.vyper.vyper_contract.VyperContract'> Type hints are not required in Python, but we will be using them more heavily later in the course. For now, we can ignore them.
