# Amazon Keyspaces code examples for the SDK for Python
## Overview
Shows how to use the AWS SDK for Python (Boto3) to work with Amazon Keyspaces (for Apache Cassandra).
<!--custom.overview.start-->
<!--custom.overview.end-->
_Amazon Keyspaces is a scalable, highly available, and managed Apache Cassandra-compatible database service._
## ⚠ Important
* Running this code might result in charges to your AWS account. For more details, see [AWS Pricing](https://aws.amazon.com/pricing/) and [Free Tier](https://aws.amazon.com/free/).
* Running the tests might result in charges to your AWS account.
* We recommend that you grant your code least privilege. At most, grant only the minimum permissions required to perform the task. For more information, see [Grant least privilege](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#grant-least-privilege).
* This code is not tested in every AWS Region. For more information, see [AWS Regional Services](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services).

## Run the examples
### Instructions
<!--custom.instructions.start-->
<!--custom.instructions.end-->
#### Hello Amazon Keyspaces
This example shows you how to get started using Amazon Keyspaces.
```
python hello.py
```
#### Learn the basics
This example shows you how to do the following:
- Create a keyspace and table. The table schema holds movie data and has point-in-time recovery enabled.
- Connect to the keyspace using a secure TLS connection with SigV4 authentication.
- Query the table. Add, retrieve, and update movie data.
- Update the table. Add a column to track watched movies.
- Restore the table to its previous state and clean up resources.
<!--custom.basic_prereqs.keyspaces_Scenario_GetStartedKeyspaces.start-->
<!--custom.basic_prereqs.keyspaces_Scenario_GetStartedKeyspaces.end-->
Start the example by running the following at a command prompt:
```
python scenario_get_started_keyspaces.py
```
<!--custom.basics.keyspaces_Scenario_GetStartedKeyspaces.start-->
<!--custom.basics.keyspaces_Scenario_GetStartedKeyspaces.end-->
### Tests
⚠ Running tests might result in charges to your AWS account.
To find instructions for running these tests, see the [README](../../README.md#Tests)
in the `python` folder.
