How can I handle errors in Python Lambda functions?

You can handle errors in Python Lambda functions using try-except blocks. This allows you to catch exceptions and manage them gracefully.

Can you give me an example of using try-except in a Lambda function?

Sure! Here's a simple example:

import json

def lambda_handler(event, context):
    try:
        # Your code here
        result = 1 / 0  # This will raise a ZeroDivisionError
        return {
            'statusCode': 200,
            'body': json.dumps(result)
        }
    except ZeroDivisionError:
        return {
            'statusCode': 400,
            'body': json.dumps({'error': 'Division by zero error'})
        }

What should I do if I want to log errors?

You can use the logging module to log errors. Just add a logging statement in the except block to capture the error details.

Is there a way to return custom error messages?

Yes, you can return custom error messages in the response body of your Lambda function, as shown in the example.
