Fix async client streaming responses example in README.md

[whichxjy]

Confirm this is an issue with the Python library and not an underlying OpenAI API

• This is an issue with the Python library

Describe the bug

The current code example in README.md for streaming responses with the async client will raise an exception because it is missing an await and should use async for instead of for.

Current example:

import asyncio
from openai import AsyncOpenAI

client = AsyncOpenAI()

async def main():
    stream = client.responses.create(
        model="gpt-4o",
        input="Write a one-sentence bedtime story about a unicorn.",
        stream=True,
    )

    for event in stream:
        print(event)

asyncio.run(main())

This will raise an exception.
It should be:

import asyncio
from openai import AsyncOpenAI

client = AsyncOpenAI()

async def main():
    stream = await client.responses.create(
        model="gpt-4o",
        input="Write a one-sentence bedtime story about a unicorn.",
        stream=True,
    )

    async for event in stream:
        print(event)

asyncio.run(main())

Thanks! Will be fixed in the next release 37d0b25

@RobertCraigie Appreciate the speedy update! Just noticed there's still one line that needs an await: client.responses.create => await client.responses.create
