How to notify myself when a python script runs into an error or just stops?

To notify yourself when a Python script encounters an error or stops unexpectedly, you can implement a mechanism that sends an email, text message, or any other form of notification. Here's a step-by-step guide on how to achieve this using email notifications:

Setting Up Email Notifications

Step 1: Install Required Libraries

You'll need the smtplib library for sending emails. This is part of Python's standard library, so typically no installation is required.

Step 2: Create a Function to Send Email

Create a function that sends an email notification when called. You'll need an SMTP server to send emails. Here's an example using Gmail's SMTP server:

import smtplib from email.mime.text import MIMEText from email.mime.multipart import MIMEMultipart def send_email(subject, body): sender_email = "your_email@gmail.com" receiver_email = "recipient_email@example.com" password = "your_password" message = MIMEMultipart() message["From"] = sender_email message["To"] = receiver_email message["Subject"] = subject message.attach(MIMEText(body, "plain")) try: with smtplib.SMTP_SSL("smtp.gmail.com", 465) as server: server.login(sender_email, password) server.sendmail(sender_email, receiver_email, message.as_string()) print("Email notification sent successfully.") except Exception as e: print(f"Failed to send email notification: {e}")

Replace your_email@gmail.com, recipient_email@example.com, and your_password with your own email credentials. Note that using Gmail for sending emails requires enabling "Less secure app access" in your Google Account settings or setting up an App Password.

Step 3: Implement Error Handling in Your Script

Modify your Python script to include error handling and call the send_email function when an error occurs:

try: # Your main script logic here # For example: result = 1 / 0 # Example of causing an error except Exception as e: send_email("Python Script Error", f"Error encountered: {str(e)}") # Optionally: Log the error for further investigation print(f"Error encountered: {str(e)}") # Optionally: Raise the error to stop script execution raise

In this example:

  • Replace result = 1 / 0 with your actual script logic.
  • The send_email function is called in the except block when an exception (Exception) occurs.
  • You can customize the subject and body of the email (subject and body arguments in send_email).

Step 4: Notify on Script Start and Stop

To notify yourself when the script starts and stops (successfully), you can also include notifications at the beginning and end of your script:

def notify_script_start(): send_email("Python Script Started", "Your Python script has started.") def notify_script_complete(): send_email("Python Script Completed", "Your Python script has completed successfully.") # Call these functions at the beginning and end of your script notify_script_start() # Your main script logic here notify_script_complete()

Notes:

  • Security: Avoid hardcoding sensitive information like passwords directly in your script. Use environment variables or configuration files with restricted access.

  • Error Handling: Customize error handling to suit your specific application's needs. You may want to log errors to a file or database for later analysis.

  • Alternative Services: Instead of email, you can use services like Twilio for SMS notifications or integrate with messaging platforms like Slack or Telegram for notifications.

By implementing these steps, you can set up email notifications to alert yourself when a Python script encounters an error or completes its execution. Adjust the implementation based on your specific requirements and preferred notification methods.
