Create automation script.
Write:
Create a Python 3.12 automation script that reads product data from a CSV file, validates missing fields, downloads product images from provided URLs, resizes the images, stores them in organized folders, generates a summary report, handles errors gracefully, and includes logging and unit tests.
Detailed prompts help Cursor AI generate more complete and reliable solutions.
Real-World Example
Imagine you're building a Python-based Inventory Automation System for a retail company.
The system must:
- Import product information from Excel files.
- Validate product records.
