⚡ Prank App – System Warning Demo

A fun and visually dynamic Python Tkinter application that simulates a system warning screen with flashing borders, progress effects, speech, and sound.
Created by Md Anayet Hossen as a learning and demonstration project for Tkinter UI, threading, and audio handling in Python.

🚀 Features

• Fullscreen GUI with animated flashing border
• Color-changing warning icon (rainbow cycle)
• Real-time progress simulation with emoji
• Voice announcements using pyttsx3
• Beep sound effects using winsound
• Multithreaded design for smooth animation
• Safe exit shortcut (Ctrl + 0)

---

🧠 Learning Goals

This project demonstrates:

• Tkinter GUI layout & styling
• Python multithreading
• Sound handling in Windows
• Text-to-speech integration
• Event binding and UI control

🛠️ Requirements

Install dependencies before running:

pip install pyttsx3

(winsound is built-in on Windows)

---

▶️ How to Run

1. Download or clone this repository
2. Open a terminal in the project directory
3. Run the script:

python "System-Warning.py"

4. To safely exit the demo, press:

   Ctrl + 0

🗜️ Convert Python Script to Windows .exe

Nice — converting a Python script into a Windows .exe is straightforward.
The most common tool is PyInstaller.
Below are concise, copy-pasteable commands for both Command Prompt (cmd) and PowerShell, plus helpful tips and common gotchas.

---

⚡ Quick Steps (Recommended)

1. Open cmd or PowerShell.
2. (Optional but recommended) Create & activate a virtual environment.
3. Install PyInstaller:

   pip install pyinstaller

4. Build the .exe with PyInstaller.
5. Find your executable inside the dist\ folder.

---

🧩 Example — Basic Console Program

Assume your script is System-Warning.py.

Command Prompt:

python -m pip install --upgrade pip
python -m pip install pyinstaller
python -m PyInstaller --onefile "System-Warning.py"

PowerShell:

python -m pip install --upgrade pip
python -m pip install pyinstaller
python -m PyInstaller --onefile "System-Warning.py"

After this, the executable will be at:

dist\System-Warning.exe

---

⚙️ Common Useful PyInstaller Options

Option	Description
--onefile	Bundle into a single .exe (recommended for distribution)
--windowed / --noconsole	For GUI apps (no console window)
--icon=app.ico	Attach an icon (use .ico format)
--add-data "src;dest"	Include data files (use ; on Windows)
--hidden-import modulename	Fix missing imports
--clean	Remove temporary build files before building
--noconfirm	Overwrite previous builds without asking

Example with icon:

python -m PyInstaller --onefile --windowed --icon="C:\path\to\app.ico" "System-Warning.py"

PowerShell note for --add-data quoting:

python -m PyInstaller --onefile --add-data 'C:\path\to\data\myfile.dat;data' "System-Warning.py"

---

💡 For Apps Using Tkinter, PyQt, pandas, numpy, etc.

PyInstaller usually detects these automatically.
If not, add manual hints:

python -m PyInstaller --onefile --hidden-import=some_module "System-Warning.py"

For data files, use:

python -m PyInstaller --onefile --add-data "assets;assets" "System-Warning.py"

---

🧰 Creating & Using a Virtual Environment (Recommended)

Command Prompt:

python -m venv venv
venv\Scripts\activate
pip install pyinstaller
python -m PyInstaller --onefile "System-Warning.py"

PowerShell:

python -m venv venv
.\venv\Scripts\Activate.ps1
pip install pyinstaller
python -m PyInstaller --onefile "System-Warning.py"

If activation is blocked:

Set-ExecutionPolicy RemoteSigned

(Run as Administrator and understand the implications before changing execution policy.)

---

📦 Where to Find the Built .exe

After running PyInstaller:

• ✅ dist\System-Warning.exe — final executable
• 🧩 build\... — build intermediates
• ⚙️ System-Warning.spec — configuration file (editable for advanced builds)

To clean up:

rmdir /s /q build dist
del System-Warning.spec

---

🧪 Testing and Distribution

• Test the .exe on a machine without Python installed
• Some antivirus software may flag unsigned executables
• Code sign your exe if you plan broad distribution
• Single-file .exes are larger because they bundle the Python runtime

---

🧯 Troubleshooting

• If your exe crashes, rebuild without --windowed to see the error:

  python -m PyInstaller --onefile "System-Warning.py"

• Run from CMD to read any error messages.
• Check missing resources (--add-data) or hidden imports.

---

🔄 Alternatives

Other tools exist (like cx_Freeze, py2exe),
but PyInstaller remains the most popular and simplest for most needs.
