# Python in Excel: Field Guide & Practice Lab for AI-assisted xlwings Lite

I am sharing my workflow and documents for using AI to reliably generate xlwings Lite Python code. This is not a theoretical guide. It's a set of practical tools and hard rules which I use day to day in my client projects.

**What's in the xlwings Lite Practice Lab:**

**1. AI Coder Instruction File:** My personal 1,855-line directive file. This is the core context you feed the AI to ensure it get clean, reliable xlwings Lite code.

**2. Step-by-Step Field Guides:** Three hands-on modules (Data Manipulation, Cleaning, Campaign Build) with the exact workbooks, guides and codes I use to test and validate.

**3. Live Apps:** xlwings Lite apps: web scrapers, database connect, AI schema detection, machine learning, quants reports

**The Core Protocol for AI code generation**

**1. Show - Context is King:** Give the AI everything - images, schemas, rules.

**2. Tell - Instruct, Don't Assume:** Be direct and iterate. One instruction is never enough.

**3. Inspect - Trust, but Verify:** All AI output must be validated. It makes mistakes.

**How to get the materials**

Go to [app.tigzig.com](http://app.tigzig.com) (Path: xlwings Lite Practice Lab)

All guides, workbooks, apps and the AI instruction file are available for download.
