Python Essentials for AI

Crash kit

# basics you will use daily

cfg = {"model": "gpt-4o-mini", "k": 4}

def chunk(text, n=200):
    return [text[i:i+n] for i in range(0, len(text), n)]

with open("docs.txt") as f:
    docs = f.read()

print(f"loaded {len(docs)} chars, {len(chunk(docs))} chunks")

Learn: f-strings, list/dict comps, requests, json, os.getenv, pip install -r requirements.txt, python -m venv .venv.

If you can read/write files, call APIs, and loop dicts, you can build AI apps.
