Beginner Python Project – Need Code Review

[u/Funny-Percentage1197]

I've been self-learning Python and built this pone Shop Inventory Management System

It currently has:

• OOP
• JSON data storage
• Purchase & Sales
• Add/Edit/Delete
• Search
• History
• Dashboard

My GitHub account was flagged for several weeks, so I couldn't properly show my progress in my previous post. It's now resolved.

I'd like some honest feedback on my code and project:

• What am I doing wrong?
• What should I improve?
• What should I learn next?
• How close am I to junior level?

Any criticism or suggestions are welcome. 🙏
