Smart Device Controller 🎮

A Python implementation of a smart device controller created as part of the EPAI (Extensive Python AI) course. This project demonstrates advanced Python concepts including class attributes, callable classes, and function attributes.

🌟 Features

• Class-based smart device implementation
• Device status management and tracking
• Built-in device counter
• Callable class functionality
• Function attributes for device information
• Comprehensive test coverage

🧩 Class Structure

SmartDevice Class

The main class that implements smart device functionality:

device = SmartDevice(device_name="Living Room Light", model_number="LRL001", is_online=False)

Key Components:

1. Class Attributes

   • device_count: Tracks total number of devices created

2. Instance Attributes

   • device_name: Name of the device
   • model_number: Device model number
   • is_online: Device online status
   • status: Dictionary storing device status attributes

3. Methods

   • update_status(attribute, value): Update device status
   • get_status(attribute): Retrieve status attributes
   • toggle_online(): Toggle device online state
   • reset(): Reset device to default state

4. Special Features

   • Callable class implementation
   • device_info function attribute

🚀 Usage Examples

# Create a new device
device = SmartDevice("Kitchen Light", "KL100")

# Update device status
device.update_status("battery", 85)
device.update_status("temperature", 24.5)

# Get specific status
battery_level = device.get_status("battery")  # Returns 85

# Toggle device online status
device.toggle_online()

# Use callable instance
print(device())  # Prints formatted device name and model

# Get device info using function attribute
info = device.device_info()

🧪 Testing
