Getting Started with Boto3

If you have ever wondered how to control AWS services using Python, then Boto3 is your magic wand! 🎩✨

What is Boto3?

Boto3 is the official AWS SDK for Python that helps you talk to AWS services like S3, EC2, Lambda, and more using simple Python code.

Imagine you have a remote control to manage AWS instead of clicking buttons on the AWS website. Boto3 gives you that power!

Installing Boto3

Before we begin, install Boto3 using pip:

pip install boto3

Make sure you also configure your AWS credentials. If you haven't, run:

aws configure

It will ask for your AWS Access Key and Secret Key (you get these from AWS IAM).

Example 1: List All S3 Buckets 📦

Want to see all your S3 buckets? Here's how:

import boto3

s3 = boto3.client('s3')  # Create an S3 client
response = s3.list_buckets()

for bucket in response['Buckets']:
    print(bucket['Name'])

This prints all your S3 bucket names. Simple, right?

Example 2: Upload a File to S3 🏗️

Let's upload a file to an S3 bucket:

s3.upload_file('myfile.txt', 'my-bucket-name', 'uploaded-file.txt')

This uploads myfile.txt from your computer to an S3 bucket as uploaded-file.txt.

Example 3: Start an EC2 Instance ⚡

Want to launch a cloud server? Try this:

ec2 = boto3.client('ec2')
response = ec2.run_instances(
    ImageId='ami-12345678',  # Replace with a real AMI ID
    InstanceType='t2.micro',
    MinCount=1,
    MaxCount=1
)
print("Instance started!", response['Instances'][0]['InstanceId'])

This starts an EC2 instance with a given Amazon Machine Image (AMI).

Wrapping Up 🎯

With Boto3, you can automate AWS tasks using Python. Try exploring more services like Lambda, DynamoDB, and SNS.
