Beginner Bootcamp: Python
 **Project:** Digital Marketplace **Project Description:** Use Python to create a decentralized application (smart contract + front-end) of a digital marketplace, in which you will be able to list your digital products (assets) to sell, define a price, and allow end users to buy them. **Time: 10:00 AM EST** each day. **Agenda:** * Session 1 (July 29th): Designing & deploying a digital marketplace smart contract with Python. * Session 2 (July 30th): Testing methods within your Python smart contract * Session 3 (July 31st): Building a front-end for your smart contract using TypeScript. * Session 4 (August 01st): Integrating both the smart contract and front-end **Prerequisites: ** * [VS Code](https://code.visualstudio.com/) (Recommended) * [Git](https://git-scm.com/downloads) * [Docker Desktop](https://www.docker.com/products/docker-desktop/) * [Python 3.10+](https://www.python.org/downloads/) * [NodeJS](https://nodejs.org/en/download) _Installation Guides_ ([macOS](https://www.youtube.com/watch?v=zsurtpCGmgE), [Windows](https://www.youtube.com/watch?v=22RvINnZsRo)) **Why Algorand?** Algorand is an enterprise-grade programmable layer-1 blockchain – the perfect place to start (or continue) your blockchain journey. * Blocks on Algorand are processed in under 3 seconds. * The Algorand network can process more than 10,000 transactions per second, all with instant finality. * The cost per transaction is 0.001 Algo (just a fraction of a cent). * Algorand is carbon-neutral and built environmentally friendly from the ground up. * Testing on Algorand is fast and cost-efficient, allowing you to innovate without friction. Plus, it has a wealth of developer tooling, tutorials, and documentation. Ready for the best bit? If you’re a Python or TypeScript dev, you don’t need to learn a new language because you can build on Algorand in Python and TypeScript. It’s easy to get building thanks to [AlgoKit](https://developer.algorand.org/algokit/?utm_source=devportal&utm_medium=bootcamp_landingpage&utm_campaign=algokit) (our solution to speed up your Web3 building process).
