Introduction to AWS and Python

Overview of AWS Services

Amazon Web Services (AWS) is a comprehensive cloud computing platform that offers a wide array of services such as computing power, storage options, and networking capabilities. AWS services are categorized into various domains including Compute, Storage, Database, Networking, and Machine Learning.

Introduction to Boto3

Boto3 is the AWS Software Development Kit (SDK) for Python. It allows Python developers to write software that makes use of services like Amazon S3 and Amazon EC2. Boto3 provides an easy-to-use interface to interact with AWS services programmatically.

Setting Up AWS Credentials

Before you start using Boto3, you need to set up your AWS credentials. This can be done by creating an AWS Identity and Access Management (IAM) user with the necessary permissions and configuring the AWS CLI.

• Install AWS CLI if not already installed: pip install awscli
• Configure the CLI: aws configure

aws configure
AWS Access Key ID [None]: YOUR_ACCESS_KEY
AWS Secret Access Key [None]: YOUR_SECRET_KEY
Default region name [None]: us-west-2
Default output format [None]: json        

Example: Listing S3 Buckets

import boto3

# Create a Boto3 session
session = boto3.Session(
    aws_access_key_id='YOUR_ACCESS_KEY',
    aws_secret_access_key='YOUR_SECRET_KEY',
    region_name='us-west-2'
)

# Use the session to create an S3 client
s3 = session.client('s3')

# List all S3 buckets
response = s3.list_buckets()
for bucket in response['Buckets']:
    print(bucket['Name'])        

This script creates a session with your AWS credentials and lists all the S3 buckets in your account.
