# mypy-boto3-pricing Mypy-friendly auto-generated type annotations for `boto3 pricing 1.10.28` service.

Install `boto3-stubs` for `pricing` service. ```bash pip install boto3-stubs[mypy-boto3-pricing] ``` Use `boto3` as usual in your project and enjoy type checking. ```python import boto3 # Use this client as usual, now mypy can check if your code is valid. client = boto3.client("pricing") # works for session as well session = boto3.session.Session(region="us-west-1") session_client = session.client("pricing") ``` ### Code auto-complete Not a single Python IDE supports `Literal` type overloads yet (but in `VSCode` support is just around the corner). Meanwhile, to have a nice auto-complete you can explicitly set types to help your IDE to get methods, arguments etc. ```python import boto3 from mypy_boto3.pricing import Client from mypy_boto3.pricing.paginator import DescribeServicesPaginator # now you have auto-complete for methods, arguments and even return types client: Client = boto3.client("pricing") # even for paginators describe_services_paginator: DescribeServicesPaginator = client.get_paginator("describe_services") ``` ## How it works Fully automated [builder](https://github.com/vemel/mypy_boto3) carefully generates type annotations for each service, patiently waiting for `boto3` updates. It delivers a drop-in type annotations for you and makes sure that: - Latest version of `boto3` is used. - Each public class and method of every `boto3` service gets valid type annotations extracted from latest documentation (blame `botocore` docs if types are incorrect). - Type annotations include up-to-date documentation. - Code is processed by [black](https://github.com/psf/black) for readability.
