How to access S3 objects using the AWS SDK for Python (Boto3)?

You can access S3 objects using the AWS SDK for Python (Boto3) by following these steps:

Install Boto3: Make sure you have Boto3 installed. You can install it using pip by running the following command:

pip install boto3

Configure AWS credentials: Set up your AWS credentials by either creating a credentials file (~/.aws/credentials) or setting environment variables with your access key and secret key.
Import Boto3: Import Boto3 library in your Python script:

import boto3

Create an S3 client: Create an S3 client by initializing a boto3.client object with the service name 's3':

s3 = boto3.client('s3')

Access S3 objects: You can now access S3 objects using various methods provided by the S3 client object. For example, to list all objects in a bucket, you can use the list_objects_v2 method:

response = s3.list_objects_v2(Bucket='your_bucket_name')
for obj in response['Contents']:
    print(obj['Key'])

Download an object: To download an object from S3, you can use the download_file method:

s3.download_file('your_bucket_name', 'your_object_key', 'local_file_path')

Upload an object: To upload a file to S3, you can use the upload_file method:

s3.upload_file('local_file_path', 'your_bucket_name', 'your_object_key')

These are just a few examples of how you can access S3 objects using the AWS SDK for Python (Boto3). You can explore more features and methods provided by the SDK in the official documentation: https://boto3.amazonaws.com/v1/documentation/api/latest/guide/s3.html
