Your task is to generate a complete, copy-pasteable Python project for a "Bar Stock Exchange" system. This system consists of a Tkinter GUI for user interaction and a Streamlit web dashboard for real-time visualization, synchronized via a JSON file. # Operational Rules & Constraints 1. **Architecture**: - Create three files: `dynamic_pricing_gui.py` (Tkinter), `streamlit_app.py` (Streamlit), and `main.py` (Launcher). - Use a JSON file (`price_data.json`) to persist and share state between the GUI and the web app. - `main.py` must use the `subprocess` module to launch both the GUI and the Streamlit app simultaneously. Ensure the Streamlit app terminates when the GUI is closed. 2. **Data Schema (Default Configuration)**: - **Section 1 (Pintjes)**: Buttons "1 P" (€1.80), "2 P" (€3.60), "3 P" (€5.40), "4 P" (€7.20), "5 P" (€9.00). - **Section 2 (Frisdrank)**: Buttons "Cola", "Cola Zero", "Ice-Tea", "Ice-Tea Green", "Fanta" (all €1.80). - **Section 3 (Zware Bieren)**: Buttons "Duvel" (€3.00), "Duvel Citra" (€3.50), "Westmalle" (€3.50), "Karmeliet" (€3.00), "Hapkin" (€2.50), "Omer" (€3.00), "Chouffe Rouge" (€3.50), "Kasteel Rouge" (€3.50), "Ter Dolen" (€3.00), "Tongerlo" (€3.00). - **Section 4 (Wijn etc)**: Buttons "Witte Wijn", "Rose Wijn", "Rode Wijn", "Belini" (all €3.00), "Aperol" (€7.00), "Cava" (€3.00). 3. **Pricing Logic**: - Implement a click counter for each item. - **Trigger**: When an item is clicked 5 times. - **Action**: Increase the price of the clicked item by €0.20. Decrease the price of all other items in the same section by €0.05. - **Constraint**: Prices must not fall below €0.00. - **Scope**: Logic applies independently to each section. - **Persistence**: Save updated prices to the JSON file immediately after every change. 4. **GUI Requirements (`dynamic_pricing_gui.py`)**: - **Theme**: Dark Grey background with Green accents. - **Layout**: 4 distinct sections (LabelFrames) with clear boundaries. - **Buttons**: Large size, rounded edges (simulated via padding/borderwidth), ample spacing between buttons. - **Controls**: Include a "Reset Prices" button that reverts all items to their default values and updates the JSON file. 5. **Dashboard Requirements (`streamlit_app.py`)**: - Display real-time bar charts for each section. - Auto-refresh or poll the JSON file to reflect changes immediately. # Communication & Style Preferences - Provide the full code for all three files without placeholders like "put the other part of the code here". - Ensure the code is ready to run immediately after pasting. - Use clear variable names and comments explaining the JSON synchronization logic. ## Triggers - python bar stock exchange system - dynamic pricing gui and streamlit dashboard - tkinter streamlit json sync project - bar price manager python code - real-time pricing dashboard with gui --- Source attribution: ECNU-ICALK Original project: https://github.com/ECNU-ICALK/AutoSkill License: MIT License information: https://opensource.org/license/mit Original upstream instructions; downloaded from Dave AI. ## Upstream license notice MIT License Copyright (c) 2026 Gabriel Moreira Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
