Type annotations for boto3.DynamoDBStreams 1.14.3 service, generated by mypy-boto3-buider 2.2.0
Project description
mypy-boto3-dynamodbstreams
Type annotations for boto3.DynamoDBStreams 1.14.3 service compatible with mypy, VSCode, PyCharm and other tools.
Generated by mypy-boto3-buider 2.2.0.
More information can be found on boto3-stubs page.
How to install
Make sure you have mypy installed and activated in your IDE.
Install boto3-stubs
for DynamoDBStreams
service.
python -m pip install boto3-stubs[dynamodbstreams]
How to use
Client annotations
DynamoDBStreamsClient
provides annotations for boto3.client("dynamodbstreams")
.
import boto3
from mypy_boto3_dynamodbstreams import DynamoDBStreamsClient
from mypy_boto3_dynamodbstreams.type_defs import IdentityTypeDef, ...
client: DynamoDBStreamsClient = boto3.client("dynamodbstreams")
# now client usage is checked by mypy and IDE should provide code auto-complete
# works for session as well
session = boto3.session.Session(region="us-west-1")
session_client: DynamoDBStreamsClient = session.client("dynamodbstreams")
Typed dictionations
mypy_boto3_dynamodbstreams.type_defs
module contains structures and shapes assembled
to typed dictionaries for additional type checking.
def get_structure() -> IdentityTypeDef:
return {
...
}
Dynamic type annotations
mypy_boto3
command generates boto3.client/resource
type annotations for
mypy_boto3_dynamodbstreams
and other installed services.
# Run this command after you add or remove service packages
python -m mypy_boto3
Generated type annotations provide overloads for boto3.client
and boto3.resource
,
boto3.Session.client
and boto3.Session.resource
functions,
so explicit type annotations are not needed.
mypy
supports function overloads as expectedPyCharm
also supports function overloads, but consumes a lot of RAM, use carefully if you have many services installedVSCode
does not currently support function overloads, use explicit type annotations
# Type is discovered correctly by mypy and PyCharm
# VSCode still needs explicit type annotations
client = boto3.client("dynamodbstreams")
session_client = boto3.Session().client("dynamodbstreams")
