ComputeOptimizerClient
✓ from mypy_boto3_compute_optimizer import ComputeOptimizerClient
Import the typed client for Compute Optimizer to annotate boto3.client('compute-optimizer').
DescribeRecommendationSummariesResponseTypeDef
✓ from mypy_boto3_compute_optimizer.type_defs import DescribeRecommendationSummariesResponseTypeDef
Import specific TypeDefs for precise response or request body annotations.
Client
✓ import boto3
from mypy_boto3_compute_optimizer import Client as ComputeOptimizerClientType
✗ from mypy_boto3_compute_optimizer.client import ComputeOptimizerClient
While importing Client directly from the 'client' submodule works, the top-level import is generally preferred and more robust against internal structure changes.
This quickstart demonstrates how to initialize a `boto3` client for Compute Optimizer and use the provided type hints for both the client itself and its method responses. This enables static analysis tools like Mypy to catch potential errors at development time.
import boto3
from mypy_boto3_compute_optimizer import ComputeOptimizerClient
from mypy_boto3_compute_optimizer.type_defs import ListRecommendationSummariesResponseTypeDef
# Ensure boto3 is installed: pip install boto3 mypy-boto3-compute-optimizer
def get_compute_optimizer_summary():
# The type hint 'ComputeOptimizerClient' provides static analysis for client methods.
client: ComputeOptimizerClient = boto3.client("compute-optimizer")
# The type hint 'ListRecommendationSummariesResponseTypeDef' helps with response structure.
response: ListRecommendationSummariesResponseTypeDef = client.list_recommendation_summaries()
print("Account Recommendation Summaries:")
for summary in response.get("RecommendationSummaries", []):
print(f" Account ID: {summary.get('AccountId')}, ")
print(f" Recommendation Count: {summary.get('RecommendationCount')}")

Known issues
breakingSupport for Python 3.8 has been removed in mypy-boto3-builder version 8.12.0 and subsequent stub packages. Your project must use Python 3.9 or newer.fixUpgrade your Python environment to 3.9 or higher. For projects requiring older Python versions, use an older version of mypy-boto3-compute-optimizer (e.g., <1.42.0) if available, but this is not recommended due to lack of updates.
affects: mypy-boto3-builder >= 8.12.0, mypy-boto3-compute-optimizer >= 1.42.0
breakingTypeDef naming conventions changed in mypy-boto3-builder 8.9.0. This might affect explicit imports of TypeDefs (e.g., `CreateDistributionRequestRequestTypeDef` became `CreateDistributionRequestTypeDef`).fixIf you directly import `TypeDef` classes and encounter `ModuleNotFoundError` or `AttributeError`, check the `mypy-boto3` documentation or generated stubs for the updated naming pattern, which typically involves shorter names or `Extra` postfix moved to the end.
affects: mypy-boto3-builder >= 8.9.0, mypy-boto3-compute-optimizer >= 1.35.0 (approx.)
gotchaThis package provides type stubs only. You must also install the `boto3` library for your code to run at runtime. Without `boto3`, your application will fail with import errors.fixAlways install `boto3` alongside `mypy-boto3-compute-optimizer` (e.g., `pip install boto3 mypy-boto3-compute-optimizer`).
affects: All versions
gotchaThis is a service-specific stub package for AWS Compute Optimizer. If you need type annotations for other AWS services (e.g., S3, EC2), you must install their respective `mypy-boto3-<service-name>` packages.fixInstall the specific `mypy-boto3-<service-name>` package for each AWS service you are using in your project.
