How can I integrate a Python Lambda function with AWS services?

You can integrate a Python Lambda function with AWS services by using the AWS SDK for Python (Boto3) to interact with services like S3, DynamoDB, and more.

Can you give me an example of a Lambda function that reads from S3?

Sure! Here's a simple example:

import boto3

def lambda_handler(event, context):
    s3 = boto3.client('s3')
    bucket = 'your-bucket-name'
    key = 'your-file-key'
    response = s3.get_object(Bucket=bucket, Key=key)
    data = response['Body'].read().decode('utf-8')
    return data

What permissions do I need to access S3 from Lambda?

You need to attach an IAM role to your Lambda function with permissions like s3:GetObject for the specific bucket.

How do I deploy this Lambda function?

You can deploy it using the AWS Management Console, AWS CLI, or frameworks like Serverless or SAM.
