Python-Based Shopping Mall System with Customer and Merchant Interfaces

The project is a Python application that implements both a customer side and a merchant side for an online shopping mall.

Features include merchant registration, login, shop information management, product addition, deletion, modification, search, and transaction record viewing; and customer registration, login, product search, purchase, order cancellation, and transaction history.

Merchant side consists of shopMain.py (UI logic), the shop folder for interface code, ui2 for Qt Designer UI files, and send_data.py for JSON communication with the server.

Customer side consists of customerMain.py , the customer folder for UI code, ui1 for Qt Designer UI files, and the same send_data.py for server interaction.

Server side includes server.py , which processes requests from merchants and customers and uses mysql_op.py to operate the MySQL database.

Project execution steps: create the database and tables using mall.sql , run server.py to start the server, then run shopMain.py for merchants or customerMain.py for customers.

Interface screenshots illustrate merchant registration, login, main interface, product management, transaction viewing, and shop information, as well as corresponding customer screens for registration, login, main interface, product browsing, purchasing, and order management.
