AttributeError: module 'thread' has no attribute 'start_new_thread'

Question

I am trying to get data from an endpoint on a website using Python, here is my code:

from aiohttp import ClientSession as session

async def get_api_data(api_url):
    try:
        async with session.post(api_url, data={"limit": 10000, "page": 1}) as response:
            response.raise_for_status()
            data = asyncio.run(response.json())
            return data
    except session as e:
        print(f"Error getting API data: {e}")
        return None

asyncio.create_task(get_api_data("url"))

But I am getting this error:

AttributeError: module 'thread' has no attribute 'start_new_thread'

When I checked the debugpy.py file, here are the lines I found: I put a comment before the line causing the error, it is in the 8th line.

    if getattr(thread_module, '_original_start_new_thread', None) is None:

I updated Python (installed version 3.12.2), updated the libraries I am using, but the issue was not resolved. Can you please help me with this?

Answer 1

If any body faces the same problem:

I solved it by deleting the "thread" library (pip uninstall thread),

the threading in asyncio is conflicting with the "thread" library in Python
