Build a script to notify you of expiring warranties

Here’s a Python script that notifies you of expiring warranties by checking a local CSV file (warranties.csv) and sending a notification (via email or console alert) for items whose warranties are about to expire within a specified number of days.

✅ Script Features:

• Accepts a list of warranty items in a CSV file.

• Checks if a warranty is expiring within a set warning period (e.g., 30 days).

• Sends console alerts or email notifications.

✅ Step 1: Create a CSV File

Create a warranties.csv file like this:

csv
CopyEdit
Item,PurchaseDate,WarrantyMonths
Laptop,2023-01-15,24
Phone,2022-06-10,36
Washing Machine,2021-12-01,48

✅ Step 2: Python Script to Check and Notify

python
CopyEdit
import csv
from datetime import datetime, timedelta
import smtplib
from email.mime.text import MIMEText

# Configuration
CSV_FILE = 'warranties.csv'
DAYS_BEFORE_EXPIRY = 30
USE_EMAIL_NOTIFICATION = False  # Set to True to use email
EMAIL_SENDER = 'youremail@example.com'
EMAIL_RECEIVER = 'receiver@example.com'
SMTP_SERVER = 'smtp.example.com'
SMTP_PORT = 587
EMAIL_PASSWORD = 'yourpassword'

def read_warranties(file_path):
    warranties = []
    with open(file_path, newline='') as csvfile:
        reader = csv.DictReader(csvfile)
        for row in reader:
            item = row['Item']
            purchase_date = datetime.strptime(row['PurchaseDate'], '%Y-%m-%d')
            warranty_months = int(row['WarrantyMonths'])
            expiry_date = purchase_date + timedelta(days=warranty_months * 30)
            warranties.append({
                'item': item,
                'expiry_date': expiry_date
            })
    return warranties

def notify(item, expiry_date):
    message = f"⚠️ Warranty for '{item}' expires on {expiry_date.date()}!"
    if USE_EMAIL_NOTIFICATION:
        send_email_notification("Warranty Expiry Alert", message)
    else:
        print(message)

def send_email_notification(subject, body):
    msg = MIMEText(body)
    msg['Subject'] = subject
    msg['From'] = EMAIL_SENDER
    msg['To'] = EMAIL_RECEIVER

    with smtplib.SMTP(SMTP_SERVER, SMTP_PORT) as server:
        server.starttls()
        server.login(EMAIL_SENDER, EMAIL_PASSWORD)
        server.send_message(msg)
        print("✅ Email sent successfully")

def check_expiring_warranties():
    warranties = read_warranties(CSV_FILE)
    today = datetime.today()
    threshold_date = today + timedelta(days=DAYS_BEFORE_EXPIRY)

    for w in warranties:
        if today <= w['expiry_date'] <= threshold_date:
            notify(w['item'], w['expiry_date'])

if __name__ == "__main__":
    check_expiring_warranties()

✅ Optional: Automate with Cron (Linux/macOS) or Task Scheduler (Windows)

• Linux/macOS: Add to crontab:

  bash
  CopyEdit
  0 9 * * * /usr/bin/python3 /path/to/script.py
  

• Windows: Use Task Scheduler to run the script daily.
