Expected type 'Union[Type[ASGI2Protocol] about modern-apis-with-fastapi HOT 9 CLOSED

from modern-apis-with-fastapi.

At first I tried it the way you had it api = fastapi.FastAPI() then I tried like in the docs. api = FastAPI() changing the import to reflect the update. from fastapi import FastAPI

Hi.

Both work. They just need to be internally consistent with the import statement:

• import fastapi => api = fastapi.FastAPI()
• from fastapi import FastAPI => api = FastAPI()

I personally prefer the more namespace driven approach for most code but either should work. The error looks like you might have written: import fastapi => api = fastapi.FastAPI (without ()) the first time around.

No, haven't done that.

Oh I see what's up. I just upgraded uvicorn to the latest version and that warning showed up. Someone screwed up the type hint in uvicorn and it thinks FastAPI won't run. But it runs fine. That's some PyCharm warning but if you run the code it still works. Not sure how to address that really other than saying just ignore it or add # noinspection PyTypeChecker on the line before.

That's the thing, I can't get it to run.

from modern-apis-with-fastapi.

That is weird. Is should either crash or run but not do nothing. Exit code 0 is success. Can you add a print statement above that line to make sure it's actually running?

from modern-apis-with-fastapi.

Oh, I see your error. You have:

if __name__ == "__main":

It should be:

if __name__ == "__main__":

Next time, just type main then tab to expand out the live template and it'll write the later version.
