types-boto3 vs boto3-stubs. What is the difference?

[moffe42]

Hi,

I'm new to Python, so this might be an obvious question.

What is the difference between the types-boto3 and boto3-stub packages? They seem to be the same to me. What package should be used on new projects if they are the same?

Hello Jacob,

For new projects I recommend types-boto3. You are right, the main difference is naming, but also types-boto3 uses new packaging system with proper dynamic required packages. However, from typing perspective there should be no difference.

boto3-stubs started as a package that was written specifically for mypy. However, current version supports pylance/pyright and PyCharm typing as well. So, that was the main reason of renaming mypy_boto3_* to types_boto3_*. THis way new packages follow the same naming pattern as types-aiobotocore and types-aioboto3.

Can both be installed simultaneously or do they conflict? It looks like I have a transitive dependency on boto3-stubs but I'm using types-boto3 directly in my pyproject.toml.
