brownie VS ganache

Check out Brownie if you are familiar with python https://github.com/eth-brownie/brownie

If you are going to use Brownie in this challenge, in your virtual environment, go ahead and install Brownie, after you installed it, create a new folder called nft and inside it run the following command:

Python and Brownie ETH, or any smart contract framework

Web3.py and Brownie setup, testing and deployment

One more advice - try executing the swaps in javascript/nodejs (https://github.com/ethers-io/ethers.js/) or python (https://github.com/eth-brownie/brownie) first, can be easier to learn. Then move it into a smart contract.

Check out ETH-Brownie first of all, you're going to love it if you're a Python guy. The docs are great.

For python backend development, I really like this tool, eth-brownie.

For someone coming from Python, Vyper would be easier to learn. There is some learning material to help you start, but for more advanced concepts it might be harder to find. And some of Ethereum tools (for security, for monitoring) are built for Solidity, but in the last couple of months some of them started to include more Vyper support. And to test your contracts, and a basis dev environnement for Vyper, Brownie (https://github.com/eth-brownie/brownie) might be the best choice, since it's Python based

To set up your Ganache, head to the website, choose your operating system, download it, and then run the application. To set up your account with Metamask, do this:

Blockchain Simulator: Ganache

Learners get hands-on experience with tools like Infura and Truffle Ganache, which are some of the most popular and widely used development tools in the Ethereum ecosystem that are focused on making Solidity easy to use. And as a product of ConsenSys, the Developer Program provides a direct link to the ConsenSys ecosystem, with access to some of the best resources and tools in the industry.

We recommend using Ganache to develop your smart contract first on a local blockchain on your machine. Each account in Ganache comes pre-loaded with test Ether, so you’re all set from the start.

Remember, smart contracts are immutable. Once they are deployed on mainnet, they can’t be modified. So it’s important to make sure they work before deploying. To get around this, we will test the functionalities of our DAO on a local instance of the Ethereum blockchain. This is made possible by Truffle’s Ganache—a one-click way to create a personal and local Ethereum blockchain.

Once you have a smart contract underway, you’ll need to test it on a blockchain. This is where Ganache comes in. Ganache is a locally hosted blockchain that simulates Ethereum on your machine. It allows you to use console.log in solidity, fork mainnet (or any other Ethereum network), set mining options, and impersonate real accounts, among other things.
