Weather-based Wallpaper Changer

Description: Create a program that changes your desktop wallpaper based on the current weather.

Skills practiced: - System integration - Image handling - Conditional logic - Scheduled tasks

Sample code:

import fetch_my_weather
import os
import platform
import ctypes
import subprocess
import tempfile
from datetime import datetime

    """Get the current weather condition using structured JSON data"""
    # Get weather with metadata for better error handling
    response = fetch_my_weather.get_weather(
        format="json",  # Use structured JSON data
        with_metadata=True  # Get metadata about response
    )

    # Extract data and metadata
    metadata = response.metadata
    weather_data = response.data

    # Check if using mock data due to an error
    if metadata.is_mock and metadata.error_message:
        print(f"Note: Using mock weather data. ({metadata.error_message})")

    # Determine condition from structured data
    if weather_data.current_condition:
        current = weather_data.current_condition[0]

Note: This script attempts to work on Windows, macOS, and Linux, but platform-specific behavior might require adjustments.

Extensions: - Add custom wallpapers for different weather conditions - Create a scheduler that updates the wallpaper every few hours - Add transition effects between wallpapers
