ServiceDiscoveryClient
✓ from mypy_boto3_servicediscovery import ServiceDiscoveryClient
✗ from mypy_boto3_servicediscovery import ServiceDiscoveryClient
This quickstart demonstrates how to use `mypy-boto3-servicediscovery` to obtain a type-hinted ServiceDiscovery client from `boto3.client`. It then calls `list_namespaces` and leverages the provided type definitions for the response, enhancing code completion and static analysis.
import boto3
from mypy_boto3_servicediscovery import ServiceDiscoveryClient
from mypy_boto3_servicediscovery.type_defs import ListNamespacesResponseTypeDef
def get_servicediscovery_namespaces() -> list[str]:
# Explicit type annotation for better IDE support and type checking
client: ServiceDiscoveryClient = boto3.client("servicediscovery")
# The response object is also type-hinted
response: ListNamespacesResponseTypeDef = client.list_namespaces()
namespace_names = [ns['Name'] for ns in response.get('Namespaces', []) if 'Name' in ns]
return namespace_names
if __name__ == "__main__":
# This code requires AWS credentials to be configured (e.g., via AWS CLI, env vars)
# If no namespaces exist, it will return an empty list.
try:
namespaces = get_servicediscovery_namespaces()
print(f"ServiceDiscovery Namespaces: {namespaces}")
except Exception as e:
print(f"An error occurred: {e}")

Known issues
breakingSupport for Python 3.8 has been officially removed starting with `mypy-boto3-builder 8.12.0` (which generated this package version). Users on Python 3.8 will encounter compatibility issues.fixUpgrade your Python environment to 3.9 or newer.
affects: >= 1.42.0 (generated by builder 8.12.0)
breakingType definition (TypeDef) naming conventions were changed in `mypy-boto3-builder 8.9.0`. Shorter names are now preferred, and 'Extra' postfixes are moved. For example, `CreateDistributionRequestRequestTypeDef` became `CreateDistributionRequestTypeDef`. If your code explicitly references these generated TypeDefs, it will break.fixReview and update your explicit TypeDef references according to the new naming conventions, or rely on implicit type inference where possible.
affects: >= 1.42.0 (generated by builder 8.9.0+)
breakingThe entire `mypy-boto3-builder` ecosystem migrated to PEP 561 compliant packages in `8.12.0`. While this improves type checker discovery, it might affect custom build or package management setups that relied on older distribution methods.fixEnsure your environment uses standard `pip install` or compatible tools. If encountering issues, refer to the `boto3-stubs` documentation for detailed installation and usage instructions.
affects: >= 1.42.0 (generated by builder 8.12.0)
gotchaFor Pylint compatibility when using the `TYPE_CHECKING` flag to conditionally import types, Pylint might complain about undefined variables. A common workaround is to set types to `object` in the `else` branch.fixImplement the `if TYPE_CHECKING:` block with an `else` branch that assigns `object` to the type symbols to avoid Pylint errors. Example: `if TYPE_CHECKING: from mypy_boto3_ec2 import EC2Client else: EC2Client = object`.
affects: All versions
gotchaAlthough `boto3-stubs` offers implicit type discovery, explicit type annotations for `boto3.client(...)` and `session.client(...)` calls (e.g., `client: ServiceDiscoveryClient = session.client("servicediscovery")`) are highly recommended for optimal IDE auto-completion and robust static analysis.fixAdd explicit type annotations for client and resource objects when instantiating them from `boto3` or a `Session`.
affects: All versions
