Curriculum

Week 1: Introduction to Python and Programming Fundamentals

Topics:
- Introduction to Python: History, advantages for machine learning
- Setting Up Your Environment: Python installation, IDE selection (e.g., PyCharm, Visual Studio Code)
- Basic Programming Concepts: Variables, data types (int, float, str, bool), operators (arithmetic, logical, comparison), input/output (print(), input())
- Control Flow: Conditional statements (if-else, elif), loops (for, while), break and continue statements
Assessment:

	//! [EIP-712](https://eips.ethereum.org/EIPS/eip-712) is a standard for hashing
	//! and signing typed structured data.
	//!
	//! The implementation of the domain separator was designed to be as efficient
	//! as possible while still properly updating the chain id to protect against
	//! replay attacks on an eventual fork of the chain.
	//!
	//! NOTE: This contract implements the version of the encoding known as "v4", as
	//! implemented by the JSON RPC method [`eth_signTypedDataV4`] in MetaMask.
	//!
