What is the output of the following code?

```
import asyncio

async def read_data():
with open('data.txt', 'r') as f:
data = f.read()
return data

async def main():
data = await read_data()
print(data)

if __name__ == '__main__':
asyncio.run(main())
```

Question

If I encounter a python3 code that looks like this:
```python
async def read_data(db):
    data = await db.fetch('SELECT COUNT(*) FROM users')
    ...
```

Accepted Answer

read_data is a coroutine

Accepted Answer

The program will probably call an event loop

Answer

It is recommended to also use "yield" in the function read_data

Answer

The program will necessarily run on at least two threads

Answer

I don't know
