How to install

Generate locally (recommended)

You can generate type annotations for aiobotocore package locally with mypy-boto3-builder. Use uv for build isolation.

• Run mypy-boto3-builder in your package root directory: uvx --with 'aiobotocore==2.21.1' mypy-boto3-builder
• Select aiobotocore AWS SDK.
• Add S3 service.
• Use provided commands to install generated packages.

From PyPI with pip

Install types-aiobotocore for S3 service.

# install with aiobotocore type annotations
python -m pip install 'types-aiobotocore[s3]'

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

# standalone installation
python -m pip install types-aiobotocore-s3

How to uninstall

python -m pip uninstall -y types-aiobotocore-s3

Usage

VSCode

• Install Python extension
• Install Pylance extension
• Set Pylance as your Python Language Server
• Install types-aiobotocore[s3] in your environment:

python -m pip install 'types-aiobotocore[s3]'

Both type checking and code completion should now work. No explicit type annotations required, write your aiobotocore code as usual.

PyCharm

⚠️ Due to slow PyCharm performance on Literal overloads (issue PY-40997), it is recommended to use types-aiobotocore-lite until the issue is resolved.

⚠️ If you experience slow performance and high CPU usage, try to disable PyCharm type checker and use mypy or pyright instead.

⚠️ To continue using PyCharm type checker, you can try to replace types-aiobotocore with types-aiobotocore-lite:

pip uninstall types-aiobotocore
pip install types-aiobotocore-lite

Install types-aiobotocore[s3] in your environment:

python -m pip install 'types-aiobotocore[s3]'

Both type checking and code completion should now work.

Emacs

• Install types-aiobotocore with services you use in your environment:

python -m pip install 'types-aiobotocore[s3]'

• Install use-package, lsp, company and flycheck packages
• Install lsp-pyright package

(use-package lsp-pyright
  :ensure t
  :hook (python-mode . (lambda ()
                          (require 'lsp-pyright)
                          (lsp)))  ; or lsp-deferred
  :init (when (executable-find "python3")
          (setq lsp-pyright-python-executable-cmd "python3"))
  )

• Make sure emacs uses the environment where you have installed types-aiobotocore

Type checking should now work. No explicit type annotations required, write your aiobotocore code as usual.

Sublime Text

• Install types-aiobotocore[s3] with services you use in your environment:

python -m pip install 'types-aiobotocore[s3]'

• Install LSP-pyright package

Type checking should now work. No explicit type annotations required, write your aiobotocore code as usual.

Other IDEs

Not tested, but as long as your IDE supports mypy or pyright, everything should work.

mypy

• Install mypy: python -m pip install mypy
• Install types-aiobotocore[s3] in your environment:

python -m pip install 'types-aiobotocore[s3]'

Type checking should now work. No explicit type annotations required, write your aiobotocore code as usual.

pyright

• Install pyright: npm i -g pyright
• Install types-aiobotocore[s3] in your environment:

python -m pip install 'types-aiobotocore[s3]'

Optionally, you can install types-aiobotocore to typings directory.

Type checking should now work. No explicit type annotations required, write your aiobotocore code as usual.

Pylint compatibility

It is totally safe to use TYPE_CHECKING flag in order to avoid types-aiobotocore-s3 dependency in production. However, there is an issue in pylint that it complains about undefined variables. To fix it, set all types to object in non-TYPE_CHECKING mode.

from typing import TYPE_CHECKING

if TYPE_CHECKING:
    from types_aiobotocore_ec2 import EC2Client, EC2ServiceResource
    from types_aiobotocore_ec2.waiters import BundleTaskCompleteWaiter
    from types_aiobotocore_ec2.paginators import DescribeVolumesPaginator
else:
    EC2Client = object
    EC2ServiceResource = object
    BundleTaskCompleteWaiter = object
    DescribeVolumesPaginator = object

...

Explicit type annotations

Client annotations

S3Client provides annotations for session.create_client("s3").

from aiobotocore.session import get_session

from types_aiobotocore_s3 import S3Client

session = get_session()
async with session.create_client("s3") as client:
    client: S3Client
    # now client usage is checked by mypy and IDE should provide code completion

Paginators annotations

types_aiobotocore_s3.paginator module contains type annotations for all paginators.

    ListBucketsPaginator,
    ListDirectoryBucketsPaginator,
    ListMultipartUploadsPaginator,
    ListObjectVersionsPaginator,
    ListObjectsPaginator,
    ListObjectsV2Paginator,
    ListPartsPaginator,
)

session = get_session()
async with session.create_client("s3") as client:
    client: S3Client

    # Explicit type annotations are optional here
    # Types should be correctly discovered by mypy and IDEs
    list_buckets_paginator: ListBucketsPaginator = client.get_paginator("list_buckets")
    list_directory_buckets_paginator: ListDirectoryBucketsPaginator = client.get_paginator(
        "list_directory_buckets"
    )

    )
    list_object_versions_paginator: ListObjectVersionsPaginator = client.get_paginator(
        "list_object_versions"
    )
    list_objects_paginator: ListObjectsPaginator = client.get_paginator("list_objects")
    list_objects_v2_paginator: ListObjectsV2Paginator = client.get_paginator("list_objects_v2")
    list_parts_paginator: ListPartsPaginator = client.get_paginator("list_parts")

Waiters annotations

)

session = get_session()
async with session.create_client("s3") as client:
    client: S3Client

    # Explicit type annotations are optional here
    # Types should be correctly discovered by mypy and IDEs
    bucket_exists_waiter: BucketExistsWaiter = client.get_waiter("bucket_exists")
    bucket_not_exists_waiter: BucketNotExistsWaiter = client.get_waiter("bucket_not_exists")
    object_exists_waiter: ObjectExistsWaiter = client.get_waiter("object_exists")
    object_not_exists_waiter: ObjectNotExistsWaiter = client.get_waiter("object_not_exists")

Service Resource annotations

S3ServiceResource provides annotations for aiobotocore.resource("s3").

from aiobotocore.session import get_session

from types_aiobotocore_s3 import S3ServiceResource

session = get_session()
async with session.resource("s3") as resource:
    resource: S3ServiceResource
    # now resource usage is checked by mypy and IDE should provide code completion

    }

How it works

Fully automated mypy-boto3-builder carefully generates type annotations for each service, patiently waiting for aiobotocore updates. It delivers drop-in type annotations for you and makes sure that:

• All available aiobotocore services are covered.
• Each public class and method of every aiobotocore service gets valid type annotations extracted from botocore schemas.
• Type annotations include up-to-date documentation.
• Link to documentation is provided for every method.
• Code is processed by ruff for readability.
