Boto3 is the Amazon Web Services (AWS) SDK for Python, which allows developers to interact with various AWS services, including Amazon Elastic Compute Cloud (Amazon EC2). EC2 is a web service that provides resizable compute capacity in the cloud, allowing users to run virtual machines known as instances.

With Boto3, you can programmatically manage EC2 instances, create and manage security groups, work with Amazon Machine Images (AMIs), handle volumes, and perform many other tasks related to EC2 and other AWS services.

To use Boto3 to work with EC2, you need to have Python and Boto3 installed on your system. You can install Boto3 using pip:

Once you have Boto3 installed, you can create an EC2 client and start interacting with EC2. Here’s a basic example to get you started:

This example will describe all running instances in your AWS account and print their instance IDs, instance types, and public IP addresses (if available).

Remember that working with EC2 instances programmatically can have significant consequences on your AWS resources. Ensure you have the necessary permissions and handle your resources with care. For sensitive tasks, consider using AWS Identity and Access Management (IAM) roles with appropriate permissions.
