How to install

# Install this package
python -m pip install boto3-stubs

# Install type annotations for boto3 services you use
python -m pip install 'boto3-stubs[s3,ec2]'

# Lite version does not provide session.client/resource overloads
# it is more RAM-friendly, but requires explicit type annotations
python -m pip install 'boto3-stubs-lite[s3,ec2]'

Usage

Provides ServiceName and ResourceServiceName literals:

from typing import overload

import boto3
from botocore.client import BaseClient
from mypy_boto3.literals import ServiceName
from mypy_boto3_ec2.client import EC2Client
from mypy_boto3_ec2.literals import EC2ServiceName
from mypy_boto3_s3.client import S3Client
from mypy_boto3_s3.literals import S3ServiceName


@overload
def get_client(service_name: EC2ServiceName) -> EC2Client: ...


@overload
def get_client(service_name: S3ServiceName) -> S3Client: ...


@overload
def get_client(service_name: ServiceName) -> BaseClient: ...


def get_client(service_name: ServiceName) -> BaseClient:
    return boto3.client(service_name)


# type: S3Client, fully type annotated
# All methods and attributes are auto-completed and type checked
s3_client = get_client("s3")

# type: EC2Client, fully type annotated
# All methods and attributes are auto-completed and type checked
ec2_client = get_client("ec2")

# type: BaseClient, only basic type annotations
# Dynamodb-specific methods and attributes are not auto-completed and not type checked
dynamodb_client = get_client("dynamodb")
