Python Seat Reservation System with PySide2 GUI and Command‑Line Tools

The tutorial walks through building a self‑study room seat reservation application in Python. Required libraries (PySide2, datetime, json, argparse) are listed, and configuration files seatInf.json and occupied.json define table positions, sizes, styles, and current occupancy.

Two command‑line scripts are provided:

slotCard_in.py -i="<student_id>" – validates a campus card and displays the booked seat.

slotCard_out.py -i="<student_id>" – records a temporary leave or frees the seat.

cmd_order.py – shows available seats, accepts -i , -n , and -s arguments to create a reservation, and prints success or error messages.

The main GUI is implemented in orderSystem.py . A Window_main class creates the main window, loads the JSON data, and builds the layout with sections for title, information entry, seat selection, and a scrollable map. Seats are rendered as QPushButton widgets whose style changes based on occupancy, and clicking a seat updates the current selection.

When the user clicks the "预约" (book) button, the program checks for duplicate bookings, records the current timestamp, prints the reservation details, displays a confirmation window ( orderDataDisplay.py ), and updates the occupancy JSON.

The confirmation window ( Window_disp ) shows the student's name, ID, booking time, and seat ID, along with important notices. It also provides "暂离" (temporary leave) and "离开\取消" (leave/cancel) buttons that invoke tempLeave and leave methods to update the occupancy state.

Overall, the article demonstrates how to combine a PySide2 graphical front‑end with JSON‑based data storage and command‑line utilities to create a functional desktop reservation system.
