Python is a wide programming language that has given a lot of liberty to programmers and developers, and that’s the reason it is considered one of the best options to build applications. Several applications and web pages that we see today are designed by programmers using Python. When it is used so frequently, it is obvious to encounter errors. If you are a beginner or learner, you may halt the project to look for a solution when you get the error warning. You may encounter the exception “AttributeError: module ‘aiobotocore’ has no attribute ‘AioSession’”.

$ pip install aiobotocore

To understand it better, have a look at a basic example to import AioSession

from contextlib import AsyncExitStack

from aiobotocore.session import AioSession


# How to use in existing context manager
class Manager:
    def __init__(self):
        self._exit_stack = AsyncExitStack()
        self._s3_client = None

    async def __aenter__(self):
        session = AioSession()
        self._s3_client = await self._exit_stack.enter_async_context(session.create_client('s3'))

    async def __aexit__(self, exc_type, exc_val, exc_tb):
        await self._exit_stack.__aexit__(exc_type, exc_val, exc_tb)

# How to use with an external exit_stack
async def create_s3_client(session: AioSession, exit_stack: AsyncExitStack):
    # Create client and add cleanup
    client = await exit_stack.enter_async_context(session.create_client('s3'))
    return client


async def non_manager_example():
    session = AioSession()

    async with AsyncExitStack() as exit_stack:
        s3_client = await create_s3_client(session, exit_stack)

        # do work with s3_client
