EmmanuelSamanya/IVENTORY-MANAGEMENT-SYSTEM ? reverse-engineered prompt

Build me a simple inventory management system backend in Python for a small business.

I want to be able to add products, edit them, remove them, search for items, and see how many are in stock. It should also help track when stock is running low and make it easy to update quantities after sales or restocking. If it makes sense, include a clean way to store the data so it does not disappear when the app closes.

Keep it straightforward and easy to use, with clear responses and basic validation so bad data does not break things. If you think a small API makes sense, set that up so it can be used later with a frontend. Please organize the code neatly and add a few simple examples or tests so I can see how it works. If you need to check current docs for any Python libraries, go ahead and look them up online.
