+description: Use the LocalStack SDK for Python
+---
+
+## Introduction
+
+You can use the LocalStack SDK for Python to develop Python applications that interact with the LocalStack platform and internal developer endpoints.
+The SDK extends the REST API, offering an object-oriented interface for easier use.
+
+The LocalStack SDK for Python supports these features:
+
+- Save, list, load, and delete Cloud Pods.
+- Manage fault configurations for the Chaos API.
+- Automatically reset service states.
+- List SQS queue messages without causing side effects.
+- Retrieve and delete sent SES messages.
+
+{{< callout >}}
+This project is still in a preview phase, and will be subject to fast and breaking changes.
+{{< /callout >}}
+
+## Installation
+
+Install the latest `localstack-sdk-python` release via pip:
+
+{{< command >}}
+$ pip install --upgrade localstack-sdk-python
+{{< / command >}}
+
+## Basic Concepts
+
+LocalStack SDK for Python organizes functionality into specific modules like `aws`, `state`, `pods`, and `chaos`.
+For example, the `aws` module allows developers to initialize clients for various AWS services.
+Using the SDK in Python is straightforward: developers can import the relevant modules and initialize specific clients (e.g., `AWSClient`, `StateClient`, `PodsClient`, `ChaosClient`) to perform actions on local AWS services.
+
+### AWS endpoints
+
+#### SQS
+
+The following code snippet shows how to set up an SQS client, create a queue, send messages, and retrieve them to test local SQS interactions using LocalStack.
+
+```python
+import json
+import boto3
+import localstack.sdk.aws
+
+# Initialize LocalStack AWS client
+client = localstack.sdk.aws.AWSClient()
+
+# Set up SQS client using the LocalStack AWS client configuration
+sqs_client = boto3.client(
+    "sqs",
+    endpoint_url=client.configuration.host,
+    region_name="us-east-1",
+    aws_access_key_id="test",
+    aws_secret_access_key="test",
+)
+
+# Create an SQS queue
+queue_name = "test-queue"
+sqs_client.create_queue(QueueName=queue_name)
+queue_url = sqs_client.get_queue_url(QueueName=queue_name)["QueueUrl"]
+
+# Send messages to the queue
+for i in range(5):
+    sqs_client.send_message(
+        QueueUrl=queue_url,
+        MessageBody=json.dumps(
+            {"event": f"event-{i}", "message": f"message-{i}"}
+        ),
+    )
+
+# Retrieve messages from the queue
+response = sqs_client.receive_message(
+    QueueUrl=queue_url,
+    MaxNumberOfMessages=5
+)
+
+# Print each message body
+messages = response.get("Messages", [])
+for msg in messages:
+    print("Message Body:", msg.get("Body"))
+```
+
+The following output is displayed:
+
+```bash
+Message Body: {"event": "event-0", "message": "message-0"}
+Message Body: {"event": "event-1", "message": "message-1"}
+Message Body: {"event": "event-2", "message": "message-2"}
+Message Body: {"event": "event-3", "message": "message-3"}
+Message Body: {"event": "event-4", "message": "message-4"}
+```
+
+#### SES
+
+The following code snippet verifies an email address, sends a raw email, retrieves the message ID, and discards all SES messages afterward.
+
+```python
+import boto3
+import localstack.sdk.aws
+
+client = localstack.sdk.aws.AWSClient()
+
+# Initialize SES client
+ses_client = boto3.client(
+    "ses",
+    endpoint_url=client.configuration.host,
+    region_name="us-east-1",
+    aws_access_key_id="test",
+    aws_secret_access_key="test",
+)
+
+# Verify email address
+email = "user@example.com"
+ses_client.verify_email_address(EmailAddress=email)
+
+# Send a raw email
+raw_message_data = f"From: {email}\nTo: recipient@example.com\nSubject: test\n\nThis is the message body.\n\n"
+ses_client.send_raw_email(RawMessage={"Data": raw_message_data})
+
+# Get and print SES message IDs
+messages = client.get_ses_messages()
+for msg in messages:
+    print("Message ID:", msg.id)
+
+# Discard all SES messages
+client.discard_ses_messages()
+```
+
+The following output is displayed:
+
+```bash
+Message ID: khqzljuixhpnpejl-mnlhgajk-ebch-zfxq-orit-qgexxjlrkipo-ywgvwr
+```
+
+### State Management
+
+LocalStack provides various features for managing local state, including Cloud Pods, which allow for saving, loading, and deleting cloud states.
+
+### Cloud Pods
+
+Cloud Pods feature enables storing and managing snapshots of the current state.
+This code snippet shows listing available pods, saving a new pod, loading it, and then deleting it.
+You need to set your `LOCALSTACK_AUTH_TOKEN` in your terminal session before running the snippet.
+
+```python
+from localstack.sdk.pods import PodsClient
+
+POD_NAME = "ls-cloud-pod"
+client = PodsClient()
+
+# List all pods
+pods = client.list_pods()
+print("Pods:", pods)
+
+# Save Cloud Pod
+client.save_pod(pod_name=POD_NAME)
+print(f"Pod '{POD_NAME}' saved.")
+
+# Load Cloud Pod
+client.load_pod(pod_name=POD_NAME)
+print(f"Pod '{POD_NAME}' loaded.")
+
+# Delete Cloud Pod
+client.delete_pod(pod_name=POD_NAME)
+print(f"Pod '{POD_NAME}' deleted.")
+```
+
+The following output is displayed:
+
+```bash
+Pods: cloudpods=[PodListCloudpodsInner(max_version=1, pod_name='check-pod', last_change=None)]
+Pod 'ls-cloud-pod' saved.
+Pod 'ls-cloud-pod' loaded.
+Pod 'ls-cloud-pod' deleted.
+```
+
+### State Reset
+
+The following example demonstrates how to reset the current cloud state using LocalStack’s `StateClient`.
+
+```python
+import boto3
+from localstack.sdk.state import StateClient
+
+# Initialize StateClient and SQS client
+client = StateClient()
+sqs_client = boto3.client(
+    "sqs",
+    endpoint_url=client.configuration.host,
+    region_name="us-east-1",
+    aws_access_key_id="test",
+    aws_secret_access_key="test",
+)
+
+# Create SQS queue
+sqs_client.create_queue(QueueName="test-queue")
+url = sqs_client.get_queue_url(QueueName="test-queue")["QueueUrl"]
+print("Queue URL before reset:", url)
+
+# Reset state
+client.reset_state()
+print("State reset.")
+
+# Try to retrieve the queue URL after state reset
+try:
+    sqs_client.get_queue_url(QueueName="test-queue")
+except Exception as exc:
+    error_code = exc.response["Error"]["Code"]
+    print("Error after state reset:", error_code)
+```
+
+The following output is displayed:
+
+```bash
+Queue URL before reset: http://sqs.us-east-1.localhost.localstack.cloud:4566/000000000000/test-queue
+State reset.
+Error after state reset: AWS.SimpleQueueService.NonExistentQueue
+```
+
+### Chaos API
+
+LocalStack’s Chaos API enables fault injection to simulate issues in AWS services.
+This example shows how to add a fault rule for the S3 service, retrieve and display the rule, and finally delete it to return to normal operations.
+
+```python
+import localstack.sdk.chaos
+from localstack.sdk.models import FaultRule
+
+# Initialize ChaosClient
+client = localstack.sdk.chaos.ChaosClient()
+
+# Add a fault rule for S3
+rule = FaultRule(region="us-east-1", service="s3")
+rules = client.add_fault_rules(fault_rules=[rule])
+print("Added S3 rule:", [(r.region, r.service) for r in rules])
+
+# Retrieve and display current fault rules
+rules = client.get_fault_rules()
+print("Current rules:", [(r.region, r.service) for r in rules])
+
+# Delete the S3 fault rule
+rules = client.delete_fault_rules(fault_rules=[rule])
+print("Rules after deleting S3 rule:", [(r.region, r.service) for r in rules])
+```
+
+The following output is displayed:
+
+```bash
+Added S3 rule: [('us-east-1', 's3')]
+Current rules: [('us-east-1', 's3')]
+Rules after deleting S3 rule: []
+```
