Example Implementations

End-of-Week Report Script

python
# generate-end-of-week-report.py
import json
from datetime import datetime, timedelta
import sqlite3

def generate_end_of_week_report():
    conn = sqlite3.connect('/var/data/app.db')
    cursor = conn.cursor()
    
    # Get data from this week (Monday to Friday)
    end_date = datetime.now()
    start_date = end_date - timedelta(days=5)
    
    cursor.execute('''
        SELECT 
            COUNT(*) as total_transactions,
            SUM(amount) as total_revenue,
            COUNT(DISTINCT user_id) as unique_customers,
            AVG(amount) as avg_transaction_value
        FROM transactions
        WHERE created_at >= ? AND created_at < ?
    ''', (start_date, end_date))
    
    metrics = cursor.fetchone()
    
    report = {
        'week_start': start_date.strftime('%Y-%m-%d'),
        'week_end': end_date.strftime('%Y-%m-%d'),
        'generated_at': datetime.now().strftime('%Y-%m-%d %H:%M:%S'),
        'metrics': {
            'total_transactions': metrics[0],
            'total_revenue': round(metrics[1], 2) if metrics[1] else 0,
            'unique_customers': metrics[2],
            'avg_transaction_value': round(metrics[3], 2) if metrics[3] else 0
        }
    }
    
    with open(f'/var/reports/end_of_week_{end_date.strftime("%Y%m%d")}.json', 'w') as f:
        json.dump(report, f, indent=2)
    
    print(f"{datetime.now()}: End-of-week report generated")
    conn.close()

if __name__ == '__main__':
    generate_end_of_week_report()

Best Practices

  1. Workweek End: Friday 5 PM aligns with typical business day end
  2. Error Handling: Implement comprehensive error handling and logging
  3. Locking: Use file locks to prevent concurrent execution
  4. Monitoring: Set up alerts for failed weekly jobs
  5. Performance: Optimize tasks to complete efficiently

When to Use

Good for:

  • End-of-week reports
  • Weekly backups
  • Weekly summaries
  • Data archiving
  • End-of-workweek operations

Avoid for:

  • Real-time critical operations
  • Very long-running processes
