Return lists about fastapi HOT 7 CLOSED

You may (or I may misunderstand what you want to do) be mixing response_model and query parameters

• to return a list you should have a response_model in the route @app.put("/items/{item_id}", response_model=List[Item])
• the items: List[Item] part means you want a list of items in the query passed in the put
• the curly braces around items most likely cast items to a set (not sure about that)

or:

return {"items": items}

Working through the tutorial ( https://fastapi.tiangolo.com/tutorial/ ), hit stumbling block on first try. The command reads:
uvicorn main:app --reload
Is there some environment requirements that are not mentioned? Because that returns:
" 'uvicorn' is not recognized as an internal or external command,
operable program or batch file."
OK, so yes, I'm on a Windows desktop, That's what the employer provides ...
With uvicorn, fastapi, pydantic, etc. in /Lib/site-packages, I'm thinking that this should be equvalent:
[python directory]>python -m uvicorn main.py:main --reload
which tries to start, then error:
Error loading ASGI app. Could not import module "main.py".
OK, how about:
[python directory]>python -m uvicorn uvicorn.main.py:main --reload
Error loading ASGI app. Could not import module "uvicorn.main.py".
No? Try this:
[python directory]>python -m uvicorn. main.py
Error loading ASGI app. Import string "main.py" must be in format ":"
Right, that's why I had it the other way .., Once again:
[python directory]>python -m uvicorn uvicorn:main.py --reload
Error loading ASGI app. Attribute "main.py" not found in module "uvicorn"
Really odd, I'm looking right at it, in file explorer ...
Anyhow, pretty much stopped at the first command in the tutorial, thanks for any hints.

BTW, this editor delates some characters ( such as uderscores, around main ), and even whole words, so I won't be surprised if you can't read this as I typed it.

@zopefiend Maybe try python -m uvicorn main:main --reload
But make sure in you code, you did:

main = FastAPI()

If you did:

app = FastAPI()

you should run

python -m uvicorn main:app --reload

In main:main, the first main is the package name, or your file name in this case, and the second main is the var/obj name in the package.

If you installed them in a virtual environment, you should be able to do just unicorn main:main --reload.
