Python Basics: Types and logic for AI
Start here if you are new to Python or need a refresher. We cover variables, f-strings, conditionals, and loops — the basic building blocks for building prompt templates and retry logic.

Variables and Core Types
In AI engineering, we use Python to glue models and data together. You don't need to be a Python wizard, but you must understand how data is stored.
# Variables - no type declaration needed, but Type Hints are best practice
model: str = "claude-3-5-sonnet"
temperature: float = 0.7
max_tokens: int = 4096
is_active: bool = TrueString Formatting (f-strings): This is how you'll build 99% of your prompts.
user_input = "What is RAG?"
prompt = f"Explain this concept to a beginner: {user_input}"
