We are adding a FastAPI tutorial to our Python docs page (PR). Because it's a fairly large doc to go through, I've broken it down into smaller pieces for the TPIs. You should be able to run through the section defined in this issue without having to read any previous content from the doc, even though a bit of the context might be missing.

Set up:

1. Create a GitHuib Codespace on the main branch of this code sample: https://github.com/microsoft/python-sample-vscode-fastapi-tutorial
2. Replace the content in the main,py file with the following:

from fastapi import FastAPI

app = FastAPI()

@app.get("/")
def root():
    return {"message": "Hello World"}

3. Set the following settings in the workspace settings.json:

{
    "python.analysis.typeCheckingMode": "basic",
    "python.analysis.inlayHints.functionReturnTypes": true,
    "python.analysis.inlayHints.variableTypes": true
}

Steps:

1. Follow the "Create Routes" section in the tutorial-fastapi.md file in this PR: Add FastAPI tutorial to Python docs  vscode-docs#6760

Things we're looking for in this TPI:

• Ensure the guidance makes sense and is accurate
• Ensure you get to a successful state at each step
• Any feedback on wording/structure of this section in the tutorial

You can feel free to open issues with problems you find, or comment in the PR directly.

The tutorial is easier to follow here than in the PR.

Ran though the steps in Codespaces, and everything worked as expected 👏
