Study, Connect & Interact with a Solidity Smart Contract on Ethereum Blockchain using web3 in Python

In this challenge, we have the source code of a very simple Solidity Smart Contract. We need to setup on environemnt to interact with it and learn how we should call / use the contract functions.

I will show you the ABI, simple calls, creating transactions (build_transcation) and signing them and sending them to the contract and reading the outputs using the web3 librariy in Python.

This is a great challenge to understand the basics of the Solidity contracts on the Ethereum Blockchain and start using web3.
