Writing the voting smart contract

The application you’re going to build is a voting application. Users will vote for some proposals. In this example, you can imagine students choosing where to have a study tour for their class. Do they choose to spend it on a beach or a mountain?

You’ll build the voting decentralized application using the Ape framework that you learned in the previous chapter. So, the flow of the development should be familiar to you.

First, create a Python virtual environment:

$ python3.10 -m venv .venv
$ source .venv/bin/activate
$ (.venv) $ pip install --upgrade pip

Then you can install the Ape Framework:

(.venv) $ pip install eth-ape'[recommended-plugins]'==0.7.23

After installing the framework, you can start developing the application by creating the directory for the voting application:

(.venv) $ mkdir voting_app
(.venv) $ cd voting_app

Inside the directory, you should initialize the project using the ape command:
