Fix code example for Streaming section in Readme

[jamesev15]

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

There are a couple of errors in the examples provided for the streaming section.

1. First Issue
   This is the example code, the last line should be print(chunk.choices[0].delta.content)

from openai import OpenAI

client = OpenAI()

stream = client.chat.completions.create(
    model="gpt-4",
    messages=[{"role": "user", "content": "Say this is a test"}],
    stream=True,
)
for chunk in stream:
    if chunk.choices[0].delta.content is not None:
        print(part.choices[0].delta.content)

2. Second Issue
   This is the example code, the last line should be print(chunk.choices[0].delta.content)

from openai import AsyncOpenAI

client = AsyncOpenAI()

stream = await client.chat.completions.create(
    prompt="Say this is a test",
    messages=[{"role": "user", "content": "Say this is a test"}],
    stream=True,
)
async for chunk in stream:
    if chunk.choices[0].delta.content is not None:
        print(part.choices[0].delta.content)

To Reproduce

If you run the snippet provided, there are None values as result

from openai import OpenAI

client = OpenAI()

stream = client.chat.completions.create(
    model="gpt-4",
    messages=[{"role": "user", "content": "Say this is a test"}],
    stream=True,
)
for chunk in stream:
    if chunk.choices[0].delta.content is not None:
        print(part.choices[0].delta.content)+

Result:
