Python Seat Reservation System with PySide2 GUI and Command-Line Interface

The tutorial demonstrates how to create a seat reservation system in Python, beginning with the required libraries (PySide2, datetime, json, argparse) and a visual seat‑selection widget that can display tables, chairs, and their states.

Seat layout and occupancy data are stored in { "tableNum": 6, "tablePos": [[0.02,0.15],[0.35,0.15],[0.68,0.15],[0.02,0.65],[0.35,0.65],[0.68,0.65]], "tableSize": [[0.25,0.2],[0.25,0.2],[0.25,0.2],[0.25,0.2],[0.25,0.2],[0.25,0.2]], "tableType": [0,1,2,0,0,0], "tableSS": ["QLabel{background: rgb(245,245,245);color:rgb(92,92,92);border-radius:50px;border: 3px solid rgb(142,142,142)}","QLabel{background: rgb(245,245,245);color:rgb(92,92,92);border: 3px solid rgb(142,142,142)}","QLabel{background: rgb(221,217,195);color:rgb(92,92,92);border: 3px solid rgb(142,142,142)}"], "tableId": ["A","B","C","D","E","F"], "chairNum": [6,6,6,6,6,6], "chairPos": [...], "chairSize": [0.032,0.07], "chairSS_W": "background: rgb(242,242,242);border-radius:15px;border: 3px solid rgb(74,69,42)", "chairSS_K": "background: rgb(64,64,64);border-radius:15px;border: 3px solid rgb(74,69,42)", "chairSS_R": "background: rgb(149,55,43);border-radius:15px;border: 3px solid rgb(74,69,42)", "mapSize": [2,2] } and an {"A1": false, "A2": false, ..., "C4": true, ...} file that records which seats are occupied.

Command‑line tools are provided for various actions:

Python slotCard_in.py -i="<student_id>" – simulate card swipe to check in.

Python slotCard_out.py -i="<student_id>" – simulate card swipe to check out.

Python cmd_order.py -i="<student_id>" -n="<name>" -s="<seat>" – book a seat.

Python cmd_leave.py -i="<student_id>" -t="temp" – request a temporary leave.

Python cmd_leave.py -i="<student_id>" -t="free" – release the seat.

Sample outputs illustrate successful bookings, errors for occupied seats, invalid seat IDs, and duplicate reservations.

The GUI implementation ( orderSystem.py ) creates a main window with title, information entry fields, a scrollable map of tables and chairs, and a booking button. It loads the JSON configuration, draws each table and chair as QLabel and QPushButton widgets, and updates visual styles based on occupancy.

The result display window ( orderDataDisplay.py ) shows the booked student’s name, ID, time, and seat, and provides buttons for temporary leave and final release, along with a list of important usage notes.

Overall, the article serves as a practical guide for building a desktop reservation tool with a visual interface, JSON‑driven layout, and supporting command‑line utilities.
